You are getting on nerves!
This is where the real work of the brain occurs in these nerve cells. This is the basic unit of the nervous system.
What are neurons?
Where are neurons housed?
What is the cell body?
This system is composed of the brain and spinal cord.
What is the CNS Central Nervous System?
This is underneath the gray matter.
What is the white matter?
Neurons cannot function without the help of these cells.
What are the neuroglial cells aka neuroglis?
The axon is often covered by this fatty insulator.
What is myelin sheath?
The fluid that surrounds the spinal cord.
What is the cerebrospinal fluid?
The brain is divided into halves called.
What is hemispheres?
Pathways that connect neurons to one another.
What are neural pathways?
What are the dendrites?
The cords of the axons are this.
What are nerves?
A slice of the brain is called a
What is a cross-section?
The point at which a signal from one neuron is passed to another neuron.
What is a synapse?
Fibers project from the cell body of a neuron and conduct electrical signals away the cell body are:
What are the axons?
This system contains all the neurons involved in receiving information and sending it on to the spinal cord and brain.
What is the PNS-Peripheral Nervous System?
The hermispheres are separated by a groove.
What is the longitudinal cerebral fissure?
The end of the axon is full of tiny sacs that contain these chemicals.
What are neurotransmitters?
A sample taken from around the spinal fluid usually the area of the lower back.
What is lumbar puncture?
The outer layer of the cerebrum is covered by this?
What is gray matter?
