Study Notes

Introduction to Anatomy and Physiology

Anatomy: Derived from Greek, meaning "to cut apart"; focuses on body structure and interrelationships.
Gross Anatomy: Examines large body structures visible to the naked eye.
Microscopic Anatomy: Studies small structures (cells and tissues) through a microscope.
Physiology: Explores how body parts function, derived from Greek words for nature and study.

Organ Systems Overview

Integumentary System:
- Comprises skin, hair, and nails.
- Provides protection, regulates temperature, produces vitamin D, and houses sensory receptors.
Skeletal System:
- Comprises bones, cartilages, and joints.
- Provides structure, support, and protective functions (e.g., skull protecting the brain).
- Sites for blood cell formation and mineral storage.
Muscular System:
- Includes skeletal muscles responsible for body movement.
- Enables mobility and contraction for movement; different from muscles of the heart and hollow organs.
Nervous System:
- Consists of the brain, spinal cord, nerves, and sensory receptors.
- Acts as the fast control system responding to internal and external stimuli.
Endocrine System:
- Similar to the nervous system but operates slower.
- Comprises glands (e.g., pituitary, thyroid) producing hormones that regulate body functions.
Cardiovascular System:
- Primary organs are the heart and blood vessels.
- Distributes oxygen, nutrients, and hormones, while removing waste products.
Urinary System:
- Composed of kidneys, ureters, bladder, and urethra.
- Responsible for waste removal and regulation of water, electrolytes, and blood pressure.
Reproductive System:
- Male structures include testes, scrotum, penis; female structures include ovaries, uterus, and vagina.
- Functions to produce offspring.

Levels of Structural Organization

Chemical Level: Atoms combine to form molecules.
Cellular Level: Molecules form cells.
Tissue Level: Groups of similar cells form tissues.
Organ Level: Different tissues form organs.
Organ System Level: Different organs work together in systems.
Organismal Level: All organ systems combined form a human.

Anatomical Terminology

Serous Membranes:
- Involved in reducing friction between organs.
- Filled with serous fluid produced by membranes.
Anatomical Position:
- A standardized position for reference in anatomy; essential for accurate communication.

Homeostasis

Definition: Maintenance of a stable internal environment despite external changes.
Homeostatic Mechanisms:
- Primarily regulated by the nervous and endocrine systems.
Negative Feedback Mechanism:
- Opposes changes, maintaining a stable value (set point) through three components: receptor, control center, and effector.
Positive Feedback Mechanism:
- Increases the effect of a change, often to achieve homeostasis more effectively in certain situations.

Critical Thinking Applications

Evaluations of physiological responses to trauma and intervention treatments (e.g., blood transfusion effects).
Identification of pain locations associated with conditions like urinary bladder infections.
Understanding of the trajectory of foreign objects through body systems, such as a bullet wound scenario.
