Neurons anatomy
Neurons consist of a cell body, axons, and _________________________, which receive information.
dendrites
The skeletal muscles are controlled by the _________
somatic nervous system
consists of the midbrain, pons, and medulla oblongata
brain stem
The part of the brain that plays a major role in memory is the _____________
hippocampus
Where is vision processed in the brain?
occipital lobe
The junction between two communicating neurons is called the _______
synapse
The __________________ arc refers to a simple nerve pathway that would be involved with involuntary actions (like knee-jerk, or withdrawal)
reflex
The master gland
pituitary gland
What parts of the brain make up the limbic system
hypothalamus, hippocampus, amygdala
What connects the two hemispheres of the brain
corpus collosum
_______________ cells help destroy bacterial cells and cellular debris.
microglia
Groups of neurons that perform a common function, such as the storing of procedural memory (tying your shoe) are called neuronal ______.
pools
Which part of the brain is responsible for hearing and memory
temporal
what part of the brain regulates heart, respiration, and blood pressure
medulla oblongata
he smooth muscles and glands are controlled by the ________ nervous system.
autonomic
These cells have the same function as oligodendrocytes, but are packed within the myelin
schwann
These types of neurotransmitters increase membrane permeability, thus increasing the chance that threshold will be achieved.
exhitatory
What part of your brain is responsible for emotions
limbic system
What is the purpose of cerebral spinofluid?
protect and support central nervous system
Fluid filled cavities within the brain are called
Ventricles
These support cells are responsible for secreting the myelin sheaths: ________________
oligodendrocytes
What ions are necessary for a nerve impulse to occur?
potassium and sodium
the meninges are made up of 3 layers. list those three layers starting with the most superficial.
dura mater, Arachnoid mater, and pia mater
The part of the brain that controls higher mental activities, such as reasoning is the:
frontal lobe
The chemical that moves from the axon of one neuron across a gap to the dendrite of another is a(n)
neurotransmitter
