- largest part of human brain, carries out high thought processes
- cerebrum
- inside of cerebrum, myelinated
- white matter
- highly folded (increased SA) outside; matter is unmyelinated
- cerebral cortex (gray matter)
- between cerebrum and brain stem; consists of thalamus and hypothalamus
- diancephalon
- upperpart of diancephalon; relays incoming sensory info to cerebral cortex
- thalamus
- under thalamus; controls body temperature + maintains body homeostasis
- hypothalamus
- consists of midbrain, pons, and medulla oblongota
- brain stem
- relays visual + auditory info
- midbrain
- "bridge" cerebellum and CNS
- pons
- homeostasis (heart rate, breathing rate)
- medulla oblongata
- part of the brain below cerebral hemispheres; coordinates muscle action + receives sensory information
- cerebellum
- column of nervous tissue; carries nerve signals between body + brain
- spinal cord
- a bundle of axons and dendrites of many neurons
- nerves
- from stimulus receptors that inform the CNS of the stimuli (internal + external monitoring) from body to brain
- sensory neurons
- from the CNS to the effectors (msucles + glands) - take action on what the sensory neurons have relayed
- motor neurons
- relay info from one neuron to another
- interneurons
- division containing sensory neurons- detect info from surroundings; internal and external information; sends info to CNS
- sensory division
- consists of somatic and autonomic nervous systems
- motor division
- movement of skeletal muscles; reflexes
- somatic nervous system
- signals convey info + regulate internal environment; between CNS + smooth muscle, cardiac muscle, organs; two divisions --> sympathetic (fight or flight)and parasympathetic (rest + digest)
- autonomic nervous system
