Dendrite structure and function7/7/2023 Some are phagocytic and protect against bacterial invasion, while others provide nutrients by binding blood vessels to the neurons. Supporting, or glia, cells bind neurons together and insulate the neurons. These are the glial cells (neuroglial cells), together termed the neuroglia. Nervous tissue also includes cells that do not transmit impulses, but instead support the activities of the neurons. An extension or process called an axon carries impulses away from the cell body. It is tube- or cable-like in structure, and it transmits the information it receives from the dendrites via the cell body to the opposite end of the cell, called the axonal. The axon is a (sometimes very long) projection from the cell body. Dendrites are extensions, or processes, of the cytoplasm that carry impulses to the cell body. It controls all the functions of the cell, and this is where most of the protein synthesis occurs. The main part of the cell, the part that carries on the general functions, is the cell body. The soma has branching extensions known as dendrites. The nucleus of the neuron is located in the soma, or cell body. Then, the signal is transmitted from the cell body down the axon of the neuron. This illustration shows a prototypical neuron, which is being myelinated by a glial cell. These cells have three principal parts: the dendrites, the cell body, and one axon. The dendrite of a neuron receives signals from other neurons and transmits them to the cell body. The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. To do all these things, cells in nervous tissue need to be able to communicate with each other by way of electrical nerve impulses. The vesicles of the pre-synaptic neuron release neurotransmitters into the synapse The neurotransmitters bind with a specific receptor site on the dendrite of. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning. It is responsible for coordinating and controlling many body activities.
