Study Notes
Overview of Anatomy
- Study of the structure of organisms and their parts.
- Divided into two main branches:
- Gross Anatomy: Study of structures visible to the naked eye.
- Microscopic Anatomy: Study of structures at the cellular and tissue level.
Major Systems of the Human Body
-
Skeletal System
- Composed of bones, cartilage, and ligaments.
- Functions: supports the body, protects organs, aids in movement, stores minerals, produces blood cells.
-
Muscular System
- Composed of skeletal, smooth, and cardiac muscles.
- Functions: movement of the body, posture maintenance, heat production.
-
Circulatory System
- Composed of the heart, blood vessels, and blood.
- Functions: transports nutrients, gases, hormones, and waste throughout the body.
-
Respiratory System
- Comprises the lungs and airways.
- Functions: facilitates gas exchange (oxygen in, carbon dioxide out).
-
Digestive System
- Composed of the gastrointestinal tract and accessory organs (e.g., liver, pancreas).
- Functions: breaks down food, absorbs nutrients, eliminates waste.
-
Nervous System
- Composed of the brain, spinal cord, and nerves.
- Functions: controls body activities by transmitting signals between different parts of the body.
-
Endocrine System
- Composed of glands that secrete hormones (e.g., thyroid, adrenal).
- Functions: regulates various processes including growth, metabolism, and mood.
-
Immune System
- Composed of lymph nodes, lymphatic vessels, and immune cells.
- Functions: protects the body against pathogens and foreign substances.
-
Integumentary System
- Composed of skin, hair, nails, and glands.
- Functions: protects body from external damage, regulates temperature, provides sensory information.
-
Urinary System
- Composed of kidneys, ureters, bladder, and urethra.
- Functions: removes waste from blood, regulates fluid balance and electrolyte levels.
-
Reproductive System
- Composed of male (testes, penis) and female (ovaries, uterus) structures.
- Functions: produces sex cells and hormones, supports development of offspring.
Anatomical Terminology
-
Directional Terms:
- Superior (above), Inferior (below), Anterior (front), Posterior (back), Lateral (side), Medial (middle), Proximal (closer to trunk), Distal (farther from trunk).
-
Body Planes:
- Sagittal (divides left and right), Frontal (divides anterior and posterior), Transverse (divides superior and inferior).
Anatomical Regions
- Head and Neck: Includes skull, face, and neck structures.
- Thorax: Contains the rib cage, lungs, and heart.
- Abdomen: Houses digestive organs.
- Pelvis: Contains urinary and reproductive organs.
- Limbs: Includes upper and lower extremities (arms and legs).
Note on Homeostasis
- Anatomy works closely with physiology to maintain homeostasis, ensuring stable internal conditions despite external changes.
Anatomy Overview
- Study of organism structure and parts.
- Two main branches: gross (macroscopic) and microscopic anatomy.
Major Human Body Systems
- Skeletal System: Bones, cartilage, ligaments; supports, protects, aids movement, mineral storage, blood cell production.
- Muscular System: Skeletal, smooth, cardiac muscles; body movement, posture, heat production.
- Circulatory System: Heart, blood vessels, blood; nutrient, gas, hormone, and waste transport.
- Respiratory System: Lungs, airways; gas exchange (oxygen intake, carbon dioxide expulsion).
- Digestive System: Gastrointestinal tract and accessory organs (liver, pancreas); food breakdown, nutrient absorption, waste elimination.
- Nervous System: Brain, spinal cord, nerves; controls body functions via signal transmission.
- Endocrine System: Hormone-secreting glands (e.g., thyroid, adrenal); regulates growth, metabolism, mood, etc.
- Immune System: Lymph nodes, lymphatic vessels, immune cells; pathogen and foreign substance defense.
- Integumentary System: Skin, hair, nails, glands; protection, temperature regulation, sensory input.
- Urinary System: Kidneys, ureters, bladder, urethra; waste removal, fluid and electrolyte balance.
- Reproductive System: Male (testes, penis) and female (ovaries, uterus) organs; sex cell and hormone production, offspring development.
Anatomical Terminology
- Directional Terms: Superior/inferior (above/below), anterior/posterior (front/back), lateral/medial (side/middle), proximal/distal (closer to/farther from trunk).
- Body Planes: Sagittal (left/right), frontal (anterior/posterior), transverse (superior/inferior).
Anatomical Regions
- Head and Neck: Skull, face, neck structures.
- Thorax: Rib cage, lungs, heart.
- Abdomen: Digestive organs.
- Pelvis: Urinary and reproductive organs.
- Limbs: Upper (arms) and lower (legs) extremities.
Homeostasis
- Anatomy and physiology work together to maintain homeostasis—stable internal conditions despite external changes.
