Study Notes
Overview of Anatomy and Physiology
- Anatomy is the scientific study of body structures.
- Physiology focuses on how body structures work together to support life functions.
Areas of Specialization in Anatomy
- Gross Anatomy: Examines larger structures visible without magnification.
- Microscopic Anatomy: Studies structures requiring magnification; includes cytology (cells) and histology (tissues).
- Regional Anatomy: Explores the interrelationships of structures within specific body regions.
- Systematic Anatomy: Investigates structures that compose the body's systems.
Structural Organization of the Human Body
-
Chemical Level:
- Composed of sub-atomic particles, atoms, and molecules.
- Elements like hydrogen, iron, oxygen, carbon, nitrogen, and calcium are the basic building blocks.
- Atoms consist of protons, neutrons, and electrons.
- Molecules are formed by combinations of atoms (e.g., water, proteins).
-
Cellular Level:
- Cells are the smallest independently living units that perform all life functions.
- Structures and functions of cells are initiated by various molecules within the cytoplasm.
-
Tissue Level:
- Tissues are communities of similar cells working together.
- Progresses from cells to tissues, organs, organ systems, and finally to the organism.
-
Organ Level:
- Organs are made up of two or more tissues performing specific functions.
-
Organ System Level:
- Organ systems are groups of organs working closely together.
-
Organism Level:
- Represents the complete living entity capable of independent life.
Types of Tissues
- Epithelial Tissue: Covers body surfaces, produces secretions, and serves as a protective barrier against injuries.
- Connective Tissue: Supports and connects body parts; includes blood, bone, and cartilage, and transports or stores materials.
- Muscle Tissue: Specialized for contraction, facilitating movement; includes skeletal, cardiac, and smooth muscles.
- Nerve Tissue: Generates and transmits electrochemical impulses to regulate body functions.
Major Organ Systems
-
Integumentary System:
- Comprises the skin and subcutaneous tissue.
- Functions to prevent excessive water loss and serves as a barrier to pathogens.
-
Skeletal System:
- Includes bones and ligaments.
- Provides support and movement framework while protecting internal organs.
-
Muscular System:
- Consists of muscles and tendons.
- Responsible for movement and heat production.
-
Nervous System:
- Encompasses the brain, nerves, eyes, and ears.
- Interprets sensory information and regulates body functions via impulses.
-
Endocrine System:
- Composed of glands like the thyroid, pituitary, and adrenal glands.
- Regulates body functions through hormones affecting growth, reproduction, and metabolism.
-
Circulatory System:
- Contains blood, heart, and arteries.
- Transports oxygen and nutrients to tissues and removes waste products.
-
Lymphatic System:
- Includes the spleen and lymph nodes.
- Returns tissues to the blood and destroys pathogens to provide immunity.
-
Respiratory System:
- Features lungs, larynx, trachea, and diaphragm.
- Facilitates gas exchange between the air and blood.
-
Digestive System:
- Comprised of the stomach, liver, pancreas, and colon.
- Converts food into simple chemicals for body absorption.
-
Urinary System:
- Consists of kidneys, ureters, and the urinary bladder.
- Removes waste products from the body and regulates blood pH.
