Nervous System
The primary cell of the nervous system that send and receive electrical impulses.
Neuron
Name the structures of the CNS.
Brain & Spinal cord
The structures of the PNS.
nerves
The somatic division of the nervous system controls all of these types of movements.
Voluntary movements
PNS stands for?
CNS stands for?
peripheral nervous system
central nervous system
A supporting cell of the nervous system that monitors neuron health, nourishes neurons and removes waste.
glial cell
The meaning of CSF.
cerebrospinal fluid
The division of your peripheral nervous system that is made up of the nerves that control involuntary body responses and functions.
Autonomic nervous sysytem
The purpose of the Myelin Sheath on an axon.
What is to speed up nerve impulses
Neurons need a lot of ATP. Why?
They require a lot of energy to fire action potentials
This structure of the neuron is responsible for transmitting an action potential towards the next neuron
axon
This structure of the neuron is responsible for receiving signals from other neurons.
dendrite
What structure functions like a highway and transmits nerve impulses from the body to the brain and from the brain to the body?
The spinal cord
What are the 3 main sections of the brain?
The cerebellum, cerebrum and the brain stem
The gap between the synapse of one neuron and dendrites of the receiving neuron is called.
Synaptic Cleft
When a neuron is in "resting state"(AKA polarized) the charge inside the cell is mostly...
negative
This chemical is released across the synaptic cleft after depolarization
Neurotransmitter
The charge inside the neuron during depolarization is more?
positive
During hyperpolarization, the neuron becomes EXTRA negative. Why?
stops the action potential from moving backwards
The -------------------- returns the neuron to "resting state", which uses a lot of ATP.
Sodium Potassium Pump
Name the parts of the brainstem.
Midbrain
Pons
Medulla oblongata
This structure of the limbic system mediates emotions like fear, desire. Hint: its not fully developed in teenagers
Amygdala
These are two types of fluid/gel-like substances found in the eye.
vitreous humor
What are the 5 lobes of the brain? Name the two lobes that control executive functioning and auditory information.
Parietal
Temporal- receives and interprets auditory info
Occipital
Frontal - executive functioning
Insula
This type of receptor interprets senses of pain.
This type of receptor interprets senses of touch.
nociceptor, mechanoreceptor
