Structures
The brain, cranial nerves the spinal cord, spinal nerves, ganglia, enteric plexus and sensory receptors are.....
Structures of the Nervous System
two types of cells that can be found in the nervous system is:
Neurons and neuroglia
The CNS Stands for......
The central nervous system
what are the components of the PNS?
All of the nerves outside of the spinal cord and brain
What are the three main functions of the nervous system?
Sensory, integrative and motor
12 pairs (I-XII)
this cell provides most of the unique functions of the nervous system such as sensing, thinking, remembering, controlling muscle activity and gland secretion. What cell am I?
Neurons
The CNS is made up of?
The brain and the spinal cord
What are some components of the PNS?
Cranial Nerves, Spinal nerves, ganglia, sensory receptors
This function helps the nervous system PROCESS sensory information by analyzing and storing some of it and by making decisions for appropriate response. An example of this function would be perception.
Integrative function
There are how many pairs of spinal nerves?
31 pairs
Describe the difference between the two classifications of neurons.
Hint: Structural and functional
Structural: Multipolar, bipolar, unipolar
Functional: Sensory (afferent) Motor (efferent)
True or False: most nerve impulses that stimulate muscles to contract and glands to secrete originate in the CNSe
True.
This division of the PNS is responsible for VOLUNTARY control.
Somatic Nervous System
this function detects internal stimuli such as increase in blood acidity and external stimuli such as a raindrop landing on your arm. That information is then carried into the brain and spinal cord through cranial and spinal nerves. What function am I?
Sensory Function
This structure specifically helps with regulating the digestive system
enteric plexus
This cell does not generate or conduct nerve impulses. What kind of cell am I?
Neuroglia
True
True or false: The motor NUERONS in the ANS deal with involuntary muscle contractions of the smooth muscle and cardiac muscles.
True!
After sensory information is processed, the nervous system can activate effectors. Effectors can cause muscles to contract and glands to secrete. What function am I?
Motor Function
Ganglia
These types of neuroglia can only be found in the PNS. What two cells am I?
Schwann cells and Satellite Cells
True or False: The cranial nerves are considered part of the CNS
False :)
The parasympathetic and sympathetic division are subdivisions of what?
ANS
the conscious awareness of sensory stimuli is called:
Preception
