Study Notes
Anatomy and Physiology Overview
- Anatomy studies the structure and relationships of body parts; "ana" means "up" and "tomy" means "cut."
- Physiology examines functions of body parts in biological, mechanical, and biochemical contexts; "physi" means "nature" and "ology" means "study."
Organism Functions
- Key functions of organisms include:
- Organization
- Responsiveness
- Growth and differentiation
- Reproduction
- Movement
- Metabolism
- Excretion
Levels of Organization in the Human Body
- Hierarchical structure from smallest to largest:
- Atom: Basic matter component
- Molecule: Combination of atoms
- Macromolecule
- Organelle
- Cell: Basic life unit
- Tissue: Combination of cells
- Organ: Tissues together
- Organ System: Combined organs
- Organism: Complete systems
Anatomical Position
- Describes human positioning:
- Body upright and facing forward
- Arms at the sides
- Palms facing forward, thumbs on the outside
- Feet hip-width apart, toes forward
Integumentary System
- Largest organ, serves as a barrier between internal and external environments.
Functions
- Regulates body temperature
- Acts as a blood reservoir
- Protects against environmental hazards
- Receives cutaneous sensations
- Facilitates excretion and absorption
- Synthesizes Vitamin D
Major Organs
- Skin
- Hair
- Sweat glands
- Nails
Skin Layers
- Epidermis: Visible layer with melanocytes (skin color) and keratinocytes (waterproof barrier).
- Dermis: Contains connective tissue, blood vessels, glands, and nerve endings; houses arrector pili muscles for goosebumps.
- Hypodermis: Subcutaneous layer, consists of primarily adipose tissue and blood vessels.
Skin Appendages
- Sebaceous Glands: Oil glands that secrete sebum, keeping skin supple.
- Sudoriferous Glands: Produce sweat; types include eccrine, apocrine, mammary, and ceruminous glands (earwax).
Hair Structure
- Composed of shaft (dead cells), follicles (growth site), and bulb (blood supply).
Hair Growth Cycle
- Anagen: Active growth phase.
- Catagen: Transitional, growth halts.
- Telogen: Resting phase before shedding.
Skeletal System
- Support structure of the body influencing shape, movement, blood cell production, and mineral storage.
Functions
- Provides framework
- Protects organs (brain, spinal cord, lungs, eyes)
- Serves as levers for muscle action
- Stores minerals (calcium, phosphorus)
- Produces blood cells in marrow
Division of Skeletal System
- Axial Skeleton: 80 bones, including skull, vertebral column, and rib cage.
- Appendicular Skeleton: 126 bones, comprising limbs and girdles.
Skull Composition
- Total 29 bones:
- Cranium: 8 bones (e.g., frontal, parietal, temporal, occipital, sphenoid, ethmoid).
- Facial: 14 bones (e.g., nasal, maxillae, zygomatic, mandible).
Vertebral Column
- Adult: 26 bones; Child: 33 bones.
- Regions include cervical, thoracic, lumbar, sacrum, and coccyx.
Rib Cage
- Comprised of:
- True ribs: Directly connected to sternum
- False ribs: Connected to true ribs
- Floating ribs: Not connected at the front
Ligaments, Tendons, and Joints
- Ligaments connect bones to bones.
- Tendons connect bones to muscles.
- Joints facilitate movement; classified as immovable, slightly movable, or freely movable.
Muscular System
- Composed of muscle fibers; main functions include:
- Body movements through musculoskeletal action
- Heat production
- Maintenance of posture and support
Types of Muscles
- Types not explicitly stated; consider skeletal, smooth, and cardiac muscle classifications.
