Nervous System (AP) Flashcards
The part of the nervous system that consists of the brain and the spinal cord and acts as the command center for all communication and actions of the body
CNS/Central Nervous system
The part of the nervous system that consists of all the nerves and ganglia that branch out from the brain and spinal cord to the rest of the body, allowing signals sent by the brain to reach their target destinations
peripheral nervous system
A nerve fiber that carries a nerve impulse away from the neuron cell body
Axon
A nerve fiber that carries a nerve impulse towards the neuron cell body
dendrite
The structure that allows neurons to pass signals to other neurons, muscles, or glands
synapse
What’s this?
A neuron and all its parts
The part of the peripheral nervous system that regulates unconscious body functions such as breathing and heart rate
autonomic nervous system
What best describes the function of a nerve synapse?
Synapses allow for the passing of signals to another nerve cell or a muscle cell.
Axons are structures that carry nerve impulses away from nerve body.
Synapses are junctions between a nerve axon terminal and another cell.
The part of the peripheral nervous system that controls conscious skeletal muscle function
somatic nervous system
What is the main role of the CNS/Central Nervous System?
The central nervous system acts as the central command for all communi- cation and actions of the body.
The peripheral nervous system is responsible for transmitting the electrical signals from the brain to the rest of the body and back again.
Which of the following types of nerves sends messages to the brain?
Sensory nerves send messages to the brain
What are the differences between the CNS and PNS?
The central nervous system is comprised of the brain and spinal cord. It controls the regulation of body systems. The peripheral nervous system is made up of all of the neurons that connect the central nervous system to the rest of the body. It is responsible for sending the messages to the brain or from the brain to designated targets.
