Brain stem
relays messages between the cerebellum and upper brain stem.
pons
controls muscle tone, balance and muscle contractions
cerebellum
What are the two main things in the diencephalon
thalamus and hypothalamus
largest part of the human brain
Cerebrum
layer right beneath the skull
dura matter
Sits in the middle between the lower and upper parts of the brain and Has 4 nuclei that form the mounds on the surface
midbrain
Involved in the senses of hearing and smell and plays a role in memory and abstract thought
temporal lobe
Affects mood and body movements
thalamus
collections of neuron cell bodies and their associated neuroglia - primarily makes up the cerebrum
layer of matter that binds tightly to the brain itself
Pia matter
contains some discrete groups of gray matter that control your vital functions.
medulla oblongata
Involved in motor function and smell. Also involved in mood, emotions, foresight, and memory
frontal lobe
involved in functions of the autonomic nervous system which controls smooth muscles, cardiac muscle, and glands.
hypothalamus
bundles of parallel axons and their coverings
white matter
PNS nerve is sent into the spinal cord in order to generate response (flexor muscle)
Reflex Arc
controls heartbeat, breathing, blood pressure, swallowing, etc.
midbrain
Receives and integrates your visual sensory information
occipital robe
controls body temperature
hypothalamus
white matter between the halves of the cerebrum
corpus collosum
web like tissues below the dura matter
Arachnoid matter
Name the three parts of the brain stem in order starting with the one closest to the brain
midbrain, pons, medulla oblongata,
- involved in receiving all the sensory information except that of smell, vision, and hearing. It receives information from touch receptors from the whole body
Parietal lobe
Major relay station - Motor neurons sending actions potentials from the brain to the spinal cord and the skeletal muscles.
thalamus
This is the anatomical crossing over of neurons from left to right.
Decussation
A clear fluid that cushions and protects the brain.
cerebral spinal fluid(CSF)
