Question

Beginning with a cup positioned on a table, fill in the correct word and then place the sentences in the correct order to describe the action of taking a drink and then repositioning the cup back on the table. Assume that the elbow joint is moving through a range of motion and all other joints, including the glenohumeral joint, are immobile. Somatic efferent release neurotransmitters into the synaptic cleft, which elicits a ______ from the muscle tissue. The biceps brachii and brachialis begin to flex the elbow with greater force than the elbow extensors resulting in a(n) ____ contraction. Nearing 60 degrees of elbow flexion, the antagonistic triceps brachii continues to demonstrate the characteristic of _______. Increasing the flexion angle of the elbow, the elbow extensors exhibit _______ while the flexors eccentrically contract. Pausing at the top while a drink is taken, ________ contractions are seen in the elbow flexors

Explanation / Answer

1) Somatic efferents release neurotransmitters in the synaptic cleft which elicita a response from the muscle tissue.

2) The biceps brachii and brachialis begin to flex the elbow with greater force than the elbow extensors resulting in a(n) concentric contraction.

3) Nearing 60 degrees of elbow flexion, the antagonistic triceps brachii continues to demonstrate the characteristic of extensibility.

4) Pausing at the top while a drink is taken, isometric contractions are seen in the elbow flexors.

5) Increasing the flexion angle of the elbow, the elbow extensors exhibit elasticity while the flexors eccentrically contracts.
