2425 Intro to the Nervous System Test

Front

What is the sensory division of the peripheral nervous system?

Back

The sensory division of the peripheral nervous system is responsible for transmitting sensory information from the sense organs to the brain using sensory neurons.

Front

What are the main functions of the nervous system?

Back

The main functions of the nervous system include sensory input (detecting stimuli), motor output (causing muscle movement), and integration of sensory input and motor output.

Front

What is a neurotransmitter?

Back

A neurotransmitter is a signal molecule that transmits nerve impulses across synapses between neurons.

Front

What organs are included in the peripheral nervous system?

Back

The peripheral nervous system includes cranial nerves and spinal nerves.

Front

What are the two divisions of the autonomic nervous system?

Back

The two divisions of the autonomic nervous system are the sympathetic and parasympathetic divisions.

Front

What is the role of sensory neurons?

Back

Sensory neurons are responsible for carrying signals from sensory receptors to the central nervous system.

Front

What is the central nervous system composed of?

Back

The central nervous system is composed of the brain and spinal cord.

Front

What is the function of the autonomic nervous system?

Back

The autonomic nervous system regulates involuntary bodily functions, such as heart rate, digestion, and respiratory rate.

Front

What is the difference between the somatic and autonomic nervous systems?

Back

The somatic nervous system controls voluntary movements of skeletal muscles, while the autonomic nervous system controls involuntary functions.

Front

What is an action potential?

Back

An action potential is a rapid electrical signal that travels along the axon of a neuron, allowing for communication between neurons.
