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.
