Study Notes

Nervous System

  • Controls and coordinates body functions
  • Senses and recognizes internal and external information

Main Parts of Nervous System

  • Brain: controls body functions
  • Nerves: transmit information
  • Spinal cord: connects brain to nerves

Function

  • Enables movement
  • Allows sensing of environment through:
    • Sweat glands
    • Hair
    • Nails
    • Skin

Integumentary (Skin) System

  • First line of defense against disease
  • Regulates body temperature
  • Maintains fluid balance
  • Facilitates sensation and perception of environment
  • Protects organs
  • Removes wastes
  • Collaborates with excretory and immune systems to remove cellular wastes and protect against disease

Skeletal System

  • Supports and protects body parts
  • Maintains homeostasis
  • Produces red blood cells through red bone marrow
  • Protects vital organs:
    • Skull: brain
    • Sternum and ribs: heart and lungs
    • Vertebra: spinal cord
  • Works with muscular system to facilitate movement

Composition of Skeletal System

  • Bone
  • Connective tissue
  • Cartilage

Muscular System

  • Facilitates movement
  • Enables material transport through body

Muscles

  • Skeletal muscles: attached to bone, voluntary movement
  • Smooth muscles: found in digestive tract, uterus, and blood vessels, involuntary movement
  • Cardiac muscles: found in heart, involuntary movement

Muscles' Interactions

  • Works with skeletal system to facilitate movement
  • Collaborates with nervous system to control movement type

Kingdom Fungi

  • Eukaryotic (unicellular and multicellular organisms)

Characteristics of Fungi

  • Saprophytes: obtain food from dead organic matter
  • Parasites: feed on living organisms

Features of Fungi

  • Hypha: composed of nuclei enclosed by cell wall
  • Mycelium: mass of hyphae making up an organism
  • Septa: cross walls separating cytoplasm and nuclei into cells
  • Coenocytes: multicellular hyphae

Reproduction of Fungi

  • Fungi can reproduce sexually or asexually
  • Adult organisms are haploid (N)
  • Both sexual and asexual processes produce spores

This quiz covers the functions and main parts of the nervous system and integumentary system, including their roles in maintaining body functions and interacting with the environment.
