What is smallest structural and functional unit of the nervous system?
neuron
What is the name of smallest cell of brain?
The name of the smallest cell in the brain is a neuron. Neurons are specialized cells that transmit information throughout the nervous system.
What types of neuron is in the dorl root ganglion?
The dorsal root ganglion primarily contains sensory neurons, specifically pseudounipolar neurons. These neurons are responsible for transmitting sensory information from the periphery to the central nervous system. Their cell bodies reside in the ganglion, while their axons extend into the spinal cord and peripheral tissues.
The synaptic terminal of a sensory nueron is located where?
The synaptic terminal of a sensory neuron is located either in the dorsal root ganglion (if it is a pseudo-unipolar neuron) or directly in the spinal cord (if it is a bipolar neuron). This is where the sensory neuron connects with other neurons to transmit sensory information to the central nervous system.
What body system does the neuron belong to?
Nervous System - since brain and the spinal cord are part of it.
What is the smallest part in the nervous system?
Neuron
What is a preganglionic neuron?
A preganglionic neuron is a type of neuron located in the central nervous system that forms synapses with ganglionic neurons in the autonomic nervous system. It carries signals from the central nervous system to the ganglia, allowing for communication between the brain and the autonomic nervous system.
What is smallest structural and functional unit of the nervous system?
neuron
What is the first motor neuron in an autonomic pathway called?
The first motor neuron in an autonomic pathway is called a preganglionic neuron. It originates in the central nervous system and synapses with a postganglionic neuron in an autonomic ganglion.
Which part of a reflex arc would have a cell body in the posterior root ganglion?
The sensory (afferent) neuron has a cell body located in the posterior root ganglion of the spinal nerve. This neuron carries sensory information from the peripheral receptors to the central nervous system.
What is the term for the smallest stuctural and functional unit that makes up the nervous system?
neuron
The basic smallest unit of the nervous system is _____which is cell, having nucleus and cell membrane?
Neuron
What is the celiac ganglion?
The celiac ganglion is part of the prevertrebral ganglions. It is the ganglion that is part of the sympathetic nervous system that innervates the digestive system.
What is the unit of structure in nervous system called?
Neuron is the unit of structure in the nervous system.
What is the smallest functional unit of the nervous system?
The neuron is the smallest functional unit of the nervous system. It is responsible for transmitting information through electrical and chemical signals. Neurons make up the basic building blocks of the nervous system and are essential for communication within the brain and between the brain and the rest of the body.
What is the difference between a brain and a ganglion?
A ganglion is a description of cluster or collection of nerve cells OUTSIDE the central nervous system (or you can say that it is part of the peripheral nervous system). The brain is part of the central nervous system.
Clusters of many nerve cells are known as?
A cluster of many nerve cells outside the central nervous system is known as a ganglion (plural ganglia). A cluster of nerve cells within the central nervous system is known as a nucleus (plural nuclei).
