Autonomic Nervous System Overview

Front

Autonomic Nervous System (ANS) is also called the involuntary nervous system or general visceral motor system.

Back

The Autonomic Nervous System (ANS) is responsible for involuntary control of body functions and is also known as the general visceral motor system.

Front

Motor neurons in the Autonomic Nervous System innervate smooth muscles, cardiac muscle, and glands.

Back

The motor neurons of the ANS control smooth muscles, cardiac muscle, and glands to regulate body functions.

Front

Innervation of skeletal muscles by the somatic nervous system

Back

The somatic nervous system innervates skeletal muscles.

A diagram showing the sensory receptor, afferent neuron, interneuron, efferent neuron, and muscle in the somatic nervous system.

Back

The diagram illustrates the pathway of the somatic nervous system, where sensory receptors send signals via afferent neurons to the central nervous system (CNS), which processes the information through interneurons and sends a response via efferent neurons to skeletal muscles.

Front

Effector organs targeted by the autonomic nervous system.

Back

Effector organs include smooth muscle, cardiac muscle, glands, or other organs.

Front

Role of ganglion in the autonomic nervous system.

Back

The ganglion serves as the site where the preganglionic neuron synapses with the postganglionic neuron.

Front

Neurotransmitters involved in the autonomic nervous system.

Back

Acetylcholine (ACh) and norepinephrine (NE) are the primary neurotransmitters used in the autonomic nervous system.

Front

Characteristics of preganglionic axons.

Back

Preganglionic axons are thin and lightly myelinated, allowing them to extend to the ganglion.

Front

Function of acetylcholine (ACh) in the autonomic nervous system.

Back

Acetylcholine (ACh) is released at the synapse between the preganglionic and postganglionic neurons.

Front

Function of norepinephrine (NE) in the autonomic nervous system.

Back

Norepinephrine (NE) is released by postganglionic neurons to target effector organs.
