Nerve Cell does not Contain (a)Axon (b)Nerve endings (c)Tendons (d)Dendrites

Q. Nerve cell does not contain 

1. Axon
2. Nerve endings
3. Tendons
4. Dendrites

Answer: c) Tendons

Explanation:

A nerve cell is a type of cell that sends and receives impulses and messages from the brain to the body and vice versa (body to brain). Nerve cell contains dendrite, soma, axon, Schwann cell, nucleus, myelin sheath and nerve ending. In the options provided above only the tendon is not a part of the nerve cell. Tendon has no relation to nerve cells. Tendon acts as a connector between muscles and bones; it is a type of connective tissue which contains several strong collagen fibers. Tendons are white in color i.e. they are composed of white fibrous connective tissue. The texture of tendons is generally tough and is inelastic in nature (i.e. they are not intensely stretchy). In tendon the amount of proteoglycan is low. The basic units of the tendon are primary collagen fibers that are made up of collagen fibrils (bunches). Tendons are present all over the body of a human from head to toes. The tendon is the largest at present connecting the calf muscle to the heel bone. In a tendon collagen fiber forms a group into primary fiber bundles, secondary fiber bundles, and tertiary fiber bundles. There are five parts of tendons, these are Ensotenon, Epitenon, Paratenon, Sharpey fibers and Sheath (synovium). The human body consists of three forms of tendons like the flexor tendons, the extensor tendons, and the ligamentous tendons. 

There are several functions of the nerve cell. These are:

• The tendon helps the bones to move
• Tendon acts as a connector between skeletal muscles and bones
