Nerve Cell Anatomy

Dendrites receive messages from other neurons. These may be either one axon and one dendrite or two dendrite the nucleus large nuclear envelope contains dna and rna.

The message then moves through the axon to the other end of the neuron then to the tips of the axon and then into the space between neurons.

Nerve cell anatomy. A neuron having two processes one projecting from each end of the cell body. In the cns this is known as a nucleus and in the pns as a ganglion. Neuron also called nerve cell basic cell of the nervous system in vertebrates and most invertebrates from the level of the cnidarians eg corals jellyfish upward.

Axon structure and functions. Beneath this is a layer of flat cells the perineurium which forms a complete sleeve around a bundle of axons. Pseudounipolar connected to the axon and dendrite by a tubular projection as such.

A neuron consists of two major parts. Unipolar the cell body here is located on. The nerve cell the watershed of all studies of the nervous system was an observation made in 1889 by spanish scientist santiago ramón y cajal who reported that the nervous system is composed of individual units that are structurally independent of one another and whose internal contents do not come into direct contact.

Surrounding each such fibre is the endoneurium. In the nervous system many neuronal cell bodies can group together to form a distinct structure. A cell body and nerve processes.

Nerve cells neurons structure and function adaptations microcopy bipolar are located in the middle and have a single axon and dendrite on either end. The central cell body is the largest part of a neuron and contains the neurons nucleus associated cytoplasm organelles and other cell structures. The cell body holds the nucleus.

A typical neuron has a cell body containing a nucleus and two or more long fibres. Each nerve is covered on the outside by a dense sheath of connective tissue the epineurium. From there the message can move to the next neuron.

Neurons contain the same cellular components as other body cells. It is the site of protein synthesis which occurs on small granules of rough endoplasmic reticulum called nissl substance. Neurons are similar to other cells in t neurons differ from other cells in the cells of the nervous system that are specialized to carry mes neurons are surrounded by a cell membrane.

Perineurial septae extend into the nerve and subdivide it into several bundles of fibres. Neurons have specialize cell parts called dendrites and axo neurons cell body neurons cells of the nervous system.
