what are the characteristics of all neurons?

Neurons have many different shapes and sizes. However, a typical neuron in a vertebrate (such as a human) consists of four major regions: a cell body, dendrites, an axon , and synaptic terminals. Like all cells, the entire neuron is surrounded by a cell membrane.

Cell Shape Each cell type has evolved a shape that is best related to its function. For example, the neuron in Figure below has long, thin extensions (axons and dendrites) that reach out to other nerve cells. The extensions help the neuron pass chemical and electrical messages quickly through the body.

A group of neurons form a nerve. Neurons are the structural and functional units of the nervous system. Nerve is an enclosed, cable-like bundle of axons and nerve fibers found in the peripheral nervous system. There are three types of nerves autonomic nerves, motor nerves, and sensory nerves.

Neurons are one of two major types of nervous system cells. They are electrically excitable cells that transmit nerve impulses. Glial cells are the other major type of nervous system cells. There are many types of glial cells, and they have many specific functions.

WHAT ANATOMICAL CHARACTERISTIC DETERMINES WHETHER A PARTICULAR NEURON IS CLASSIFIED AS UNIPOLAR, BIPOLAR, AND MULTIPOLAR? THEIR DIFFERENTIATED ACCORDING TO THE NUMBER OF PROCESSES ATTACHED TO THE CELL BODY.

A neuron, neurone (old British spelling) or nerve cell, is an electrically excitable cell that communicates with other cells via specialized connections called synapses.

Neurons have TWO "processes" called axons and dendrites.... glial cells have only ONE. Neurons CAN generate action potentials... ... glial cells do NOT have chemical synapses.

The primary components of the neuron are the soma (cell body), the axon (a long slender projection that conducts electrical impulses away from the cell body), dendrites (tree-like structures that receive messages from other neurons), and synapses (specialized junctions between neurons).

1: Defining characteristics of chordates: In chordates, four common features appear at some point during development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life.

There are three major types of neurons: sensory neurons, motor neurons, and interneurons. All three have different functions, but the brain needs all of them to communicate effectively with the rest of the body (and vice versa).
1404818
Neurons have (only one / many) axon/axons. Axons are (never / frequently) branched. Dendrites have (only one / many) branch/branches.

Neurons are surrounded by a cell membrane. Neurons have a nucleus that contains genes. Neurons contain cytoplasm, mitochondria and other organelles. Neurons carry out basic cellular processes such as protein synthesis and energy production.

For neurons in the brain, at least, this isn't an easy question to answer. For the spinal cord though, we can say that there are three types of neurons: sensory, motor, and interneurons.
