Study Notes
Blood and Circulatory System
- The human body contains 8 to 10 pints of blood.
- Blood serves as a nutritive fluid in the circulatory system.
- Plasma is the fluid part of blood, transporting nutrients and waste, including carbon dioxide.
Cellular Biology
- Platelets are blood components crucial for the blood clotting process.
- Protoplasm comprises the jellylike substance within cells, containing essential food elements.
- Mitosis is the process of cell reproduction, resulting in two identical daughter cells.
Anatomy and Organs
- The sternum is a flat bone that supports the ribs.
- Organs are specialized structures composed of tissues performing specific functions.
- The nervous system controls and coordinates all body functions.
- The endocrine system regulates growth, development, and health through hormones.
Glands and Hormones
- The pituitary gland is the most complex organ of the endocrine system.
- The pancreas secretes enzymes for digesting carbohydrates, proteins, and fats.
- Hormones are secreted by endocrine glands and influence overall body welfare.
Systems and Functions
- The primary function of the respiratory system is breathing; the lymphatic/immune system protects against disease.
- The skeletal system provides a physical foundation, while the circulatory system moves blood throughout the body.
- The digestive system transforms food into nutrients and waste, and the excretory system eliminates waste.
- The reproductive system perpetuates the human race.
Muscular System
- Skeletal tissue is shaped and supported by the muscular system.
- The origin of a muscle attaches to the skeleton and remains stationary during movement.
Neurology
- Neurology is the study of the nervous system's structure, function, and pathology.
- The brain connects to the spinal cord via the brainstem.
- The central nervous system (CNS) includes the brain, spinal cord, cranial nerves, and spinal nerves.
- The autonomic nervous system controls involuntary muscles.
- There are 12 pairs of cranial nerves affecting various facial areas.
Muscles of the Face and Neck
- The occipitalis muscle draws the scalp backward; the frontalis causes forehead wrinkles.
- Orbicularis oculi closes the eyes, while buccinator compresses the cheeks.
- Muscles like the masseter and temporalis are used for chewing.
- Sternocleidomastoid muscle enables head rotation; latissimus dorsi covers the lower back.
Nerve Functions
- Reflex nerves react to stimuli causing muscle movement.
- The maxillary nerve affects the upper part of the face; the mandibular nerve affects the chin and lower lip.
- Infraorbital nerve affects the skin around the lower eyelid and upper lip, while nasal nerve impacts the nose.
Important Movements
- Abduction separates fingers, while adduction draws them together.
- Flexion occurs when bending forward and extension occurs during straightening.
- Supination is a rotational movement, while pronation turns muscles inward.
Importance for Estheticians
- Understanding anatomy and physiology helps estheticians assess the effects of services on tissues and systems.
- Knowledge of forearm muscles is important for maintaining good body mechanics.
- Massage aids in maintaining pliability in hand muscles.
