Type I cells can be further classified by the location of the soma. The basic morphology of type I neurons, represented by spinal motor neurons, consists of a cell body called the soma and a long thin axon covered by a myelin sheath. The dendritic tree wraps around the cell body and receives signals from other neurons.
It is composed of neurons, also known as nerve cells, which receive and transmit impulses to and from it , and neuroglia, also known as glial cells or glia, which assist the propagation of the nerve impulse as well as provide nutrients to the neurons. [1] Nervous tissue is made up of different types of neurons, all of which have an axon.
Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges, blood vessels, and ducts. The two main types of cells in the brain are neurons, also known as nerve cells, and glial cells, also known as neuroglia. [1]
There is a basic difference between the two groups in the placement of the nervous system within the body: protostomes possess a nerve cord on the ventral (usually bottom) side of the body, whereas in deuterostomes the nerve cord is on the dorsal (usually top) side.
A nerve is an enclosed, cable-like bundle of nerve fibers (called axons) in the peripheral nervous system. Nerves have historically been considered the basic units of the peripheral nervous system. Nerves have historically been considered the basic units of the peripheral nervous system.
Kidney and nerve tissue cells can form memories much like brain cells, one new study has found. Another recent study says that memories of obesity stored in fat tissue may be partly responsible ...
Cell types. by origin; The following is a list of nerves in the human body: ... The oculomotor nerve; The trochlear nerve; The trigeminal nerve; The abducens nerve;
Progress in defining the morphology of nerve cells has been slow in its development. It took nearly a century after the acceptance of the cell as the basic unit of life before researchers could agree upon the shape of a neuron. It was originally thought to be an independent globular corpuscle suspended along nerve fibers that looped and coiled. [3]
