Muscles

Question 1

types of muscle (7)]

Answer 1

circular

convergent

parallel

unipennate

bipentate

fusiform

multipentate

Question 2

circular muscle

Answer 2

e.g. sphincters, mouth etc.

Question 3

convergent muscle

Answer 3

These are muscles where the origin is wider than the point of insertion. This fibre arrangement allows for maximum force production.

e.g. pectoralis major

Question 4

parallel muscle

Answer 4

Parallel muscles are characterized by fascicles that run parallel to one another, and contraction of these muscle groups acts as an extension of the contraction of a single muscle fiber.

e.g. sartorius

Question 5

unipennate

Answer 5

. A type of pennate muscle wherein the muscle fibers or fascicles are all in one side of the tendon. Supplement.

e.g. extensor digitorum longus

Question 6

bipennate

Answer 6

Bipennate muscles have two rows of muscle fibres, facing in opposite diagonal directions, with a central tendon, like a feather. This allows even greater power but less range of motion.

e.g. Rectus Femoris.

Question 7

fusiform

Answer 7

are those in which all the muscle belly fibers are arranged parallel to each other.

e.g. biceps brachii.

Question 8

multipenate

Answer 8

A type of pennate muscle wherein the diagonal muscle fibers are in multiple rows with the central tendon branching into two or more tendons.

e.g. deltoid muscle
