The length force diagram, twitch time characteristics and muscle architecture are quantified.In the parallel fibered semimembranosus the length of the muscle fibres is about 70% of the muscle optimum length (the length at which the muscle performs maximal active force), while in the pennate ...
The muscle has three heads giving it three points of origin: Clavicular head - originates from the anterior surface of the clavicle (medial half). Sternocostal head - originates from the anterior surface of the sternum and costal cartilages of ribs 1-6. Abdominal (rectus) head - origin...
Name and describe the functions of the contractile, regulatory, and structural protein molecules seen in the skeletal muscle fibres. Name and describe the functions of the contractile, regulatory, and structural protein molecules seen in skeletal muscle fibres Pick one characteristic...
Electrochemical processes taking place in our body generate complex signals (hum) that are continuously being passed along the nerve fibres throughout the body. Any physical activity such as muscle movement increases hum. Here’s an auto reset proximity detector circuit that operates when it detects...

Human muscle system, the muscles of the human body that work the skeletal system, that are under voluntary control, and that are concerned with movement, posture, and balance. Broadly considered, human muscle—like the muscles of all vertebrates—is ofte
The muscle walls of the vagina are thick and elastic in order to accommodate both the movement of the penis during intercourse and the passage of a child during delivery. The muscular wall is composed of two layers of muscle fibres, a weak internal circular layer and a strong external longitu...

Themesoglealayer, which lies between the ectoderm and the endoderm (the innermost tissue layer) of coelenterates, is thin in small species and massive in large ones. It forms a flexible skeleton, associated with supporting muscle fibres on both the ectodermal and endodermal sides. In many br...
