Surrounds neuron cell bodies in peripheral nervous system
Astrocytes
surrounds neuron axons in CNS
Oligodendrocytes
contains cilia that moves cerebral spinal fluid
ependymal cells
becomes microphanges that destroy microorganisms
microglia
surrounds neuron axons in peripheral nervous system
Schwann cells
limbic structure that assists in long-term memory
hippocampus
controls pituitary gland
hypothalamus
transmits info to opposite hemisphere
corpus callosum
smooths out motor activities
cerebellum
where intersection of nerves to cords takes places
medulla oblongata
A region of the cerebral hemispheres that is an elevated ridge is a
sulcus
That the human brain has an anterior, very large collection of neurons is
cephalization
In a motor homunculus, which is largest?
foot
In a sensory homunculus, which is smallest?
elbow
If a potassium channel opens, K+ will flow
out
If a sodium channel opens, Na+ will flow
in
If a chloride channel opens, Cl- will _____ the membrane
hyperpolarization
If a calcium channel opens, the membrane will
depolarization
If the membrane becomes less positive/more negative than “at rest”
hyperpolarization
found just anterior to the central sulcus
primary motor area
a motor speech area
Broca’s area
found just under the occipital bone
primary visual area
integrates skin and skeletal input
somatosensory association area
located in temporal lobe
primary auditory area
