Neurons. There are two broad classes of cells in the nervous system: neurons, which process information, and glia, which provide the neurons with mechanical and metabolic support. Three general categories of neurons are commonly recognized (Peters, Palay, & Webster, 1976).

The internal tendon bulk is thought to contain no nerve fibres, but the epitenon and paratenon contain nerve endings, while Golgi tendon organs are present at the junction between tendon and muscle.

Nervous tissue is absent in tendon. These are made up of collagen. Tendons and muscles work together to move bones. Therefore, option C is correct.

Neurons are the central building blocks of the nervous system, 100 billion strong at birth. Like all cells, neurons consist of several different parts, each serving a specialized function ([link]).

Neurons, also known as nerve cells, send and receive signals from your brain. While neurons have a lot in common with other types of cells, they’re structurally and functionally unique. Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells.

Neurons

The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, which includes the nucleus, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).

Nerve cells with intact synapses. In the microscope, synapses from hippocampus nerve cells look like small, mushroom-shaped protuberances called dendritic spines. Nerve cells receive signals from other nerve cells via dendrites, which branch out like the branches of a tree.

Nerve cell shapes vary according to the number, branching and disposition of their projections or dendrites, collectively known as arborization. This determines their capacity for interacting with their environment and with other nerve cells or neurons, hence their computational ability and roles.

Nerve cells are shaped like long wires so they can carry messages form one end of the body to the other. Some nerve cells in the brain can keep their information and send out messages for a long time. “B” is a small blood vessel that brings food and oxygen to the nerve cells.

The target cells of neurons include other nerve cells in the brain, spinal cord, and autonomic ganglia, and the cells of muscles and glands throughout the body.

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).
