Study Notes
Organ Systems and Examples
- The digestive system exemplifies an organ system.
- The heart serves as an example of an organ.
Functions of Body Systems
- The skeletal system provides structure, protection, support, and produces blood cells.
- The muscular system enables movement of the body and internal organs.
- The nervous system sends and receives messages throughout the body.
- The respiratory system brings oxygen into the body and removes carbon dioxide.
- The circulatory system transports nutrients, oxygen, and waste through the blood.
- The digestive system breaks down food to absorb nutrients.
- The lymphatic system defends against infection and maintains fluid balance.
- The endocrine system produces hormones that regulate body functions.
- The urinary system removes waste from the blood and regulates fluid balance.
- The integumentary system (skin) protects the body and regulates temperature.
- The reproductive system enables reproduction of offspring.
Skeletal System Importance
- The skeletal system supports the body, protects organs, allows movement, stores minerals, and makes blood cells in the bone marrow.
- The skeletal system supports the body, protects internal organs, assists with movement, produces blood cells, and stores calcium, phosphorus, magnesium, and sodium.
Homeostasis Definition
- Homeostasis is the body’s ability to maintain a stable internal environment despite changes in external conditions.
Movement Systems
- The skeletal and muscular systems work together to enable body movement.
Nervous System Functions
- The nervous system senses stimuli, processes information, and responds with actions.
- Voluntary control: Moving an arm to wave.
- Involuntary control: Your heart beating.
Muscular System Types
- Skeletal muscle is attached to bones and facilitates voluntary movement.
- Smooth muscle is found in internal organs like the stomach and operates involuntarily.
- Cardiac muscle is exclusively in the heart and functions involuntarily.
Integumentary System
- The skin (integumentary system) acts as the body's first line of defense.
- Accessory organs include sensory receptors, hair, nails, oily glands, and sweat glands.
Respiratory System Organs
- Organs include the nose, nasal cavity, pharynx, larynx, trachea, bronchi, lungs, and diaphragm.
Nerve Cell Signal Relay
- When a prick is felt, nerve cells relay information to the brain.
Lymphatic and Circulatory Systems
- The lymphatic system collects excess fluid from tissues and returns it to the circulatory system; it also helps fight infections carried in the blood.
- Lymph does not circulate like blood but moves in one direction from its collection in tissues to its return in the blood.
- There are no lymphatic pumps, and valves in the lymphatic vessels prevent the backward movement of lymph.
- The lymphatic system filters blood by destroying pathogens.
Anatomical Terms
- Anterior refers to the front of the body.
- Posterior refers to the back of the body.
- The popliteus is posterior to the patella.
- Superior refers to above or toward the head.
- Inferior refers to below or toward the feet.
- Lateral refers to away from the midline of the body.
- Medial describes the middle or direction toward the middle of the body.
- Proximal describes a position in a limb that is nearer to the point of attachment to the trunk of the body.
- Distal describes a position in a limb that is farther from the point of attachment to the trunk of the body.
Tissue Types
- The four types of tissue are connective tissue, epithelial tissue, muscle tissue, and nerve tissue.
Cell Membrane
- The cell membrane is the thin, flexible outer layer of a cell.
- It protects the cell and controls what goes in and out.
Nucleus
- The nucleus is the control center of the cell.
- It holds the cell’s DNA (genetic material) and tells the cell what to do.
Mitochondria
- The mitochondria are known as the “powerhouses” of the cell.
- They produce energy (ATP) from food so the cell can work and stay alive.
Mitosis
- Mitosis is the process by which a cell divides to make two identical new cells.
- It’s how the body grows and heals.
- It’s how the body grows and heals.
Cell Metabolism
- Cell metabolism refers to all the chemical reactions happening in a cell that keep it alive.
- This includes breaking down food for energy and building parts the cell needs.
Anatomy and Physiology for Estheticians
- Knowledge of anatomy and physiology provides the foundation for performing quality esthetic services.
- Estheticians primarily work with skeletal or voluntary muscles.
Anatomy and Physiology Definitions
- Anatomy studies organs and systems of the body.
- Physiology studies the structure and function of organs and systems.
- Gross anatomy studies structures visible to the naked eye.
- Histology studies structures visible only through a microscope.
Metabolism Explained
- Metabolism is the chemical processes in cells providing nutrients for cell growth or reproduction.
- Metabolism comprises anabolism and catabolism.
Anabolism
- Anabolism builds larger molecules from smaller ones, like proteins from amino acids.
- Anabolism supports growth of new cells, maintains body tissues, and stores energy.
- The liver and kidneys producing glucose from non-carbohydrate sources is an example of anabolism.
Catabolism
- Catabolism breaks down molecules, like nutrients for glucose.
- Catabolism happens when you digest food and molecules break down for energy use.
- Large, complex molecules break down into smaller, simple ones during catabolism.
Types of Tissue
- Epithelial tissue covers and protects body surfaces and internal organs.
- Connective tissue supports, protects, and holds tissues together.
- Nerve tissue carries messages to and from the brain, coordinating body functions.
- Muscle tissue contracts to produce movement.
- Liquid connective tissues carry food, waste products, and hormones.
Tissues and Organs
- Tissues make up organs.
- Organs working together to perform specific functions form body systems.
Skeletal System Details
- Lacrimal bones are the smallest and most fragile facial bones, situated at the front inside part of the eye socket.
- The hyoid bone is a U-shaped bone at the base of the tongue that supports the tongue and its muscles.
- Bones are connected to each other by ligaments.
Muscular System Details
- The human body has over 630 muscles, accounting for approximately 40% of body weight.
- Out of the over 630 muscles, 30 are facial muscles.
- Skeletal or voluntary muscles contract with conscious thought, while smooth or involuntary muscles are not under conscious control.
- Cardiac muscles are specific to heart function and are not under conscious control.
- Skeletal muscles are attached to bones and are controlled by thought processes.
- Nerve impulses trigger a reaction from the muscle, which contracts, moving the bone or joint it is associated with.
- Muscles are connected to bones by tendons.
- There are over 230 moveable and semi-moveable joints in the body.
- The frontalis muscle raises the eyebrows, draws the scalp forward, and causes wrinkles in the forehead.
- The occipital muscle is a broad muscle that covers the top of the skull and draws the scalp backward; it has two parts, occipitalis and frontalis.
- The corrugator muscle is located beneath the frontalis and orbicularis oculi; it draws the eyebrow down and wrinkles the forehead vertically.
- The levator palpebrae superioris muscle controls the eyelid and can be easily damaged during makeup application.
- The orbicularis oris muscle circles the mouth and is responsible for closing and puckering the lips.
- The buccinator muscle compresses the cheeks and aids in chewing and whistling.
- The zygomaticus major muscle elevates the corners of the mouth and is involved in smiling.
- The levator labii superioris muscle elevates the upper lip.
- The depressor anguli oris depresses the corners of the mouth and is involved in frowning.
- The mentalis elevates and protrudes the lower lip and is involved in expressions of doubt or disdain.
- The risorius draws the corners of the mouth laterally and is involved in expressions of grinning.
Lacrimal Apparatus
- The lacrimal apparatus produces and drains tears.
- Tears (lacrimal fluid) are produced by the lacrimal glands.
Endocrine System
- The hypothalamus links the nervous system to the endocrine system via the pituitary gland and releases hormones that control the pituitary gland.
- The pituitary gland, often called the master gland, controls other endocrine glands, and produces growth hormone, thyroid-stimulating hormone, and ACTH.
- The thyroid gland regulates metabolism, produces energy, and growth, and produces T4 and T3 hormones.
- The parathyroid glands regulate calcium levels in the blood and produce parathyroid hormone.
- The adrenal glands produce hormones that regulate metabolism, immune response, and stress, including cortisol and adrenaline.
- The pancreas regulates blood sugar levels and produces insulin and glucagon.
- Gonads produce sex hormones that regulate reproductive functions, including estrogen, progesterone, and testosterone.
- The pineal gland regulates sleep-wake cycles and produces melatonin.
Digestive System
- Enzymes are proteins that speed up chemical reactions in the body, including digestion.
- Peristalsis involves involuntary muscle contractions that move food through the digestive tract.
- Bile is a digestive fluid produced by the liver that helps break down fats.
- Villi are small, finger-like projections in the small intestine that increase surface area for absorption.
Circulatory System
- Arteries carry oxygen-rich blood away from the heart.
- Veins carry oxygen-poor blood back to the heart.
- Capillaries are tiny vessels that exchange gases, nutrients, and waste.
