The part of the neuron that is covered with a myelin sheath.
AXON
what does CNS stand for?
Central Nervous System
This is the substance found between the arachnoid mater and the pia mater in the spinal cord.
CEREBROSPINAL FLUID
what is the peripheral system made of?
nerves that branch off from the spinal cord.
The basic functions of the nervous system.
RECEIVE INFO, INTERPRET &
RESPOND
What does a dendrite do?
Receives neurotransmitters from another neuron's axon terminal
The cerebral hemispheres make up this percentage of the brain.
83%
The web-like covering of the spinal cord.
ARACHNOID
what does PNS stand for?
peripheral nervous system
A shallow groove of the brain.
SULCUS
What is the purpose of the myelin sheath?
insulates axon, protects and speeds up nervous impulse
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
Which of the meninges covering the spinal cord cling to the surface closely?
PIA MATER
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 central nervous system is made of these organs
brain and spinal cord
The chemicals that are released from the axonal terminals.
NEUROTRANSMITTERS
The cavities of the brain.
VENTRICLES
This enlargement of the spinal cord is the area where the nerves that serve the lower limbs arise.
LUMBAR ENLARGEMENT
Neurons taking information back to your body are called what?
motor neurons/Efferent neurons
An elevated ridge of the brain.
GYRUS
Name the tiiiiiiny empty space between dendrites of one neuron and axon terminals of the connecting neuron
Synapse
The part of the brain that contains the pons, midbrain and the medulla oblongata.
BRAIN STEM
A rapid, predictable motor response to a stimulus that does not involve the higher brain.
REFLEX
What does the Somatic division of the nervous system control?
Skeletal Muscle- Voluntary movement of the body
