Nervous System
This system consists of the brain and spinal cord.
What is the central nervous system?
This fatty layer around the axon of a neuron increases speed of an impulse.
What is the myelin sheath?
This area is controlled by the left side of the brain.
What is the right side of the body?
These 2 structures protect the brain and spinal cord.
What are the skull and verterbal column?
This is the term for the study of the nervous system.
What is neurology?
This division of the peripheral nervous system carries nerve impulses to the voluntary skeletal muscles.
What is the somatic nervous system?
Multiple branches at the end of the neuron that carry information to the cell body.
What are dendrites?
This is the primary energy source for the brain.
An involuntary muscle reaction that is controlled by the spinal cord.
What is a reflex?
How does the cholinergic system effect our heart rate, BP, and metabolism?
This division of the peripheral nervous system carries nerve impulses to the heart, involuntary smooth muscle, and glands. It includes the parasympathetic and sympathetic nervous system.
What is the autonomic nervous system?
These function to conduct the nerve impulse away from the cell body.
What are axons?
4 lobes make up this part of the brain.
What is the cerebrum?
This condition is characterized by an excess of cerebrospinal fluid
What is hydrocephalus?
These cells hold neurons in place.
What are glial cells (neuroglia)?
This division of the autonomic nervous system carries nerve impulses to the heart, involuntary muscles, and glands during times of increased activity, danger, or stress.
What is the sympathetic nervous system? (Fight or flight response)
This chemical messenger travels across the synapse between a neuron and another neuron, muscle fiber, or gland.
What is a neurotransmitter?
This part of the brain controls body temperature, thirst/hunger sensation, and circadian rhythm. It also helps control emotions and produces hormones.
What is the hypothalamus?
This part of the brainstem contains vital centers for respirations, heart rate, and blood pressure.
What is the medulla oblongata?
This substance cushions and protects the brain and spinal cord from shock.
What is cerebrospinal fluid?
Another term for the parasympathetic nervous system.
This cell forms the myelin sheaths around axons in the peripheral nervous system.
What are Schwann cells?
This part of the brain connects the 2 hemispheres and allows them to communicate and coordinate activities.
What is the corpus callosum?
What are the 3 layers of the meninges called?
Dura mater, arachnoid mater, and pia mater
This part of the brain monitors muscle tone and position and coordinates new muscle movements
What is the cerebellum?
