Expert Solution

Explanation of Solution

Pictorial representation: Fig.1 represents the H zone though cross-section of muscle fiber.

Vander's Human Physiology, Chapter 9, Problem 1PI , additional homework tip 1

Fig.1: H zone

H zone is the central portion of the A band that is present only in the resting sarcomere. The H zone region does not have overlapping thin filament. It only has thick filament.

Expert Solution

Explanation of Solution

Pictorial representation: Fig.1 represents the I band though cross-section of muscle fiber.

Vander's Human Physiology, Chapter 9, Problem 1PI , additional homework tip 2

Fig.1: I zone

I band is the only region that contains thin filament and extends from both directions of Z disk. At the region of maximal shortening, the thin filaments of the muscle fiber are pulled parallel along the thick filaments. This leads to decrease of I bands.

Fig.1: M line

M line is the narrow, dark band in the center region of the H zone known as M line that corresponds to proteins link together at the central region of the adjacent thick filament.

Vander's Human Physiology, Chapter 9, Problem 1PI , additional homework tip 4

Fig.1: Z line

The sarcomeres are composed of thin and thick overlapping filaments. It is delineated by Z disks on both ends. These disks are composed of specialized proteins that are perpendicular to myofilaments and function as an anchor for the thin filament.
