FROG MUSCLE PHYSIOLOGY 2) What was the smallest voltage required to produce max contraction? What proportion of the muscle fibers in the muscle do you think were contracting to produce this maximal response? Muscle fibers act in response to isolated stimuli in an all or none fashion. However‚ a muscle organ‚ such as the gastrocnemius muscle‚ is composed of many individual muscle fibers. It is known that all of the fibers in a muscle do not have the same threshold and that a stimulus applied to

Intramembranous ossification forms membrane bone from fibrous connective tissue membranes‚ and results in the cranial bones and clavicles. ~Movements of Muscle~ 1) Flexion: bending a joint to decrease the angle between two bones or two body parts.

2017 Motor Unit Recruitment and Muscle Fatigue Lab Introduction Human skeletal muscles are made up of hundreds of cylindrically-shaped cells called myofibers‚ and they are bound together by connective tissue. These muscles are stimulated to contract by somatic motor nerves‚ or motor neurons‚ that carry signals in the form of nerve impulses from the brain or spinal cord‚ to the skeletal muscles. Although a motor neuron can innervate several fibers‚ each muscle fiber can only be innervated by one motor

Muscles attached to scapula: Levator scapulae origin is transverse processes of C1-C4‚ insertion at superior angle of scapula‚ it moves scapula and flexes neck. Pectoralis minor’s origin is ribs 3-5 and insertion at coracoid process of scapula‚ it depresses scapula and elevates ribs. Rhomboids Major and Rhomboids Minor’s origin at spinous processes T1-T4‚ insertion at medial border of scapula‚ they move scapula. Serratus anterior’s origin is at ribs 1-9‚ insertion is at medial border of scapula
