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
