Question

Write four differences between tendon and ligament.

Answer 1

Hint: In order to provide the body with support, shape and structures the body has certain structures called tendons and ligaments which help in these functions and are involved with muscles of the body aiding in various body functions.

Complete Answer:
Tendons and ligaments are the connective tissue which are the essential component of the skeletal and muscular system of the body. They belong to the class of Dense granular connective tissue and are required for proper functioning of skeletal and muscular systems. Though they have many similarities, differences between them exist too.

Let us make a table to find out the differences between a tendon and a ligament.

Sl.NO	TENDON	LIGAMENT
1.	Tendons are inelastic cord like structures that join the muscles to the bones of the body.	Ligament is the elastic structure that joins the bones to the bones.
2.	In tendons the content of proteoglycan is considered to be lower than the ligaments and collagen content is higher than ligaments.	The amount of proteoglycan in ligaments is higher and collagen content is lower than their content in the tendons.
3.	The fibroblasts cells of the tendons are found to be present continuously throughout their structure.	The fibroblasts of the ligaments are not continuous and are found to be scattered in their structure.
4.	Only nearly one tendon is found in one muscle.	Many ligaments are found per joint

Note: Tendons and ligaments also differ with one another in the blood supply in which tendons have heavy blood supply while ligaments usually show poor blood supply.
