Study Notes
Anatomy and Physiology Concepts
- Anatomy involves the study of the structure of the body; Physiology focuses on the functions of bodily systems.
- The chemical level consists of atoms and molecules, forming the basic structure of cells.
- The cellular level represents the fundamental unit of life.
- Tissue level includes groups of cells that perform similar functions.
- Organ level comprises tissues that work together for a specific function.
- Organ system level is a collection of organs coordinating to perform complex tasks.
- Organismic level refers to the complete organism built from various organ systems.
Human Body Systems
- Integumentary System: Regulates body temperature and protects against environmental hazards.
- Skeletal System: Provides support, protects internal organs, stores minerals, and forms blood cells.
- Muscular System: Facilitates movement and generates body heat.
- Nervous System: Handles immediate responses to stimuli.
- Endocrine System: Regulates long-term changes and functions within the body.
- Cardiovascular System: Manages internal transport of nutrients, gases, and waste products.
- Lymphatic & Immune Systems: Offers defense against diseases and returns fluids to the bloodstream.
- Respiratory System: Responsible for gas exchange between air and blood.
- Digestive System: Handles ingestion, breakdown, absorption of food, and waste elimination.
- Urinary System: Filters blood to manage water, salt balance, and waste removal.
- Reproductive System: Generates sex cells and hormones necessary for reproduction.
Homeostasis and Feedback Mechanisms
- Homeostasis is the maintenance of stable internal conditions within physiological limits.
- Homeostatic regulation involves system adjustments to maintain homeostasis.
- Receptor: Monitors changes in the environment and sends information to the control center.
- Control Center: Processes input from receptors and determines responses.
- Effector: Receives commands from the control center and implements responses.
- Feedback systems involve a sequence: stimulus -> receptor -> input -> control center -> output -> response.
Feedback Types
- Positive Feedback: Amplifies changes; example: labor contractions during childbirth.
- Negative Feedback: Counteracts changes to restore balance; example: insulin secretion in response to high blood sugar.
Anatomical Terminology
- Anatomical Position: Erect stance with feet apart, palms facing forward.
- Cranial: Refers to the upper portion of the head around the brain.
- Facial: Indicates the face area.
- Cervical: Relates to the neck region.
- Thoracic: Pertains to the chest area.
- Axillary: Refers to the armpit.
- Acromial: Related to the point of the shoulder.
- Deltoid: Describes the fleshy shoulder muscle.
- Brachial: Relates to the upper arm.
- Antebrachial: Pertains to the forearm.
- Antecubital: Refers to the front of the elbow.
- Carpal: Indicates the wrist area.
- Manual: Refers to the hand.
- Digital (Phalangeal): Pertains to the fingers or toes.
