Question

explain neuron with a labbled diagram​

Answer 1

Answer:

Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. Most neurons have a cell body, an axon, and dendrites. The cell body contains the nucleus and cytoplasm. The axon extends from the cell body and often gives rise to many smaller branches before ending at nerve terminals. Dendrites extend from the neuron cell body and receive messages from other neurons. Synapses are the contact points where one neuron communicates with another. The dendrites are covered with synapses formed by the ends of axons from other neurons.

The brain is what it is because of the structural and functional properties of interconnected neurons. The mammalian brain contains between 100 million and 100 billion neurons, depending on the species. Each mammalian neuron consists of a cell body, dendrites, and an axon.

The cell body contains the nucleus and cytoplasm. The axon extends from the cell body and often gives rise to many smaller branches before ending at nerve terminals.

Dendrites extend from the neuron cell body and receive messages from other neurons. Synapses are the contact points where one neuron communicates with another. The dendrites are covered with synapses formed by the ends of axons from other neurons.

When neurons receive or send messages, they transmit electrical impulses along their axons, which can range in length from a tiny fraction of an inch (or centimeter) to three feet (about one meter) or more. Many axons are covered with a layered myelin sheath, which accelerates the transmission of electrical signals along the axon. This sheath is made by specialized cells called glia. In the brain, the glia that make the sheath are called oligodendrocytes, and in the peripheral nervous system, they are known as Schwann cells.

The brain contains at least ten times more glia than neurons. Glia perform many jobs. Researchers have known for a while that glia transport nutrients to neurons, clean up brain debris, digest parts of dead neurons, and help hold neurons in place. Current research is uncovering important new roles for glia in brain function.

Answer 2

Answer:

A neuron is an individual specialized cell, primarily involved in transmitting information through electrical and chemical signals. They are found in the brain, spinal cord and the peripheral nerves. A neuron is also known as the nerve cell.

The structure of a neuron varies with their shape and size and it mainly depends upon their functions and their location. Neurons are the structural and functional units of the nervous system. A group of neurons form a nerve. Neurons are the structural and functional units of the nervous system. There are two types of neurons:

1- Sensory Neurons

2- Motor Neurons

The neuron is an individual specialized cell, which is also known as the nerve cell A group of neurons form a nerve.

Dendrites–A branch-like structure that functions by receiving messages from other neurons and allow the transmission of messages to the cell body.

Cell Body–Each neuron has a cell body with a nucleus, Golgi apparatus, endoplasmic reticulum, mitochondria and other components.

Axon–Axon is a tube-like structure that functions by carrying an electrical impulse from the cell body to the axon terminals to passing the impulse to another neuron.

Synapse– This structure functions by permitting the entry of a neuron to move an electrical or chemical signal from one neuron to another neuron.
