Neurons (=nerve cells) are the structural and functional unit of the neural tissue and hence the nervous system. Certain neurons may almost equal the length of the body itself. These neurons with longer processes (projections) are the longest cells in the body. Human neural system has about 100 billion neurons. Majority of the neurons occur i the brain. Fully formed neurons never divide and remain in the interphase throughout life. Shortly after birth, new neurons dont develop. Certain neurons have flask shaped cytons (cell body or soma) and are called Purkinje cells, which occur in the cerebellum of the brain.
What else can I help you with?
As part of which nervous system do postganglionic neurons release norepinephrine?
Sympathetic nervous system, which is part of autonomic nervous system.
What system comprises the sensory and motor neurons?
The peripheral nervous system comprises the sensory and motor neurons.
What are two parts of the peripheral nervous system?
The two parts of the peripheral nervous system are the somatic nervous system, responsible for voluntary movements and sensory input, and the autonomic nervous system, which regulates involuntary functions like heart rate and digestion.
What system is neurons in?
Neuron is in the Nervous System
What is the element of the nervous system?
Neurons
In contrast to the somatic nervous system the automonic nervous system?
Has two efferent neurons.
What is a specialized cell that conducts impulses through the nervous system?
The specialized cell that conducts impulses through the nervous system is called a neuron. Neurons are the building blocks of the nervous system and are responsible for transmitting electrical and chemical signals throughout the body to enable communication between different parts of the body.
The basic cell that makes up the nervous system and which receives and sends messages within that system is called a?
neuron. Neurons are specialized cells that process and transmit information through electrical and chemical signals in the nervous system. They have a unique structure that allows them to efficiently communicate with other neurons, facilitating the functioning of the nervous system.
What cells type is the conductive cell of nervous system?
The conductive cells of the nervous system are called neurons. Neurons are specialized cells that are capable of transmitting electrical impulses and information throughout the body. They play a vital role in processing and transmitting signals in the nervous system.
What system consist of sensory and motor neurons associated with voluntary actions?
The somatic nervous system consists of sensory and motor neurons that are associated with voluntary actions. Sensory neurons transmit sensory information from the body to the central nervous system, while motor neurons transmit signals from the central nervous system to muscles to initiate movement. This system allows for conscious control over skeletal muscle movement.
Where do you find a connector neurone?
Connector neurons are found in the central nervous system, where they connect sensory neurons to motor neurons or other connector neurons. These neurons play a crucial role in transmitting and integrating information within the nervous system.
What are the cells in the nervous system?
neurons and neuroglia
