What is the effector muscle for the bicep reflex?
What are the effector muscles of the biceps reflex? The biceps brachii. Triceps reflex. Produced by striking the tendon of the triceps brachii near its insertion just proximal to the olecranon. Produces a slight twitch, or extension of the forearm at the elbow joint.
What muscle is involved in the tricep reflex?
the triceps brachii muscle
The triceps reflex, a deep tendon reflex, is a reflex as it elicits involuntary contraction of the triceps brachii muscle. It is initiated by the Cervical (of the neck region) spinal nerve 7 nerve root (the small segment of the nerve that emerges from the spinal cord).
What is the response of tricep reflex?
The triceps reflex is measured by striking the triceps tendon directly with the hammer while holding the patient’s arm with your other hand. Repeat and compare to the other arm. The triceps reflex is mediated by the C6 and C7 nerve roots, predominantly by C7….Deep Tendon Reflexes.
| Rate the reflex with the following scale: | |
|---|---|
| 0 | No response |

What nerve innervates the biceps and triceps?
The musculocutaneous nerve is responsible for innervating the flexors of the arm, including the biceps brachii, coracobrachialis, and the medial aspect of the brachialis. The radial nerve innervates the triceps brachii, lateral aspect of the brachialis, anconeus, brachioradialis, and extensor carpi radialis longus.
When flexing the elbow the triceps is the and the biceps is the?
When you want to bend your elbow, your biceps muscle contracts (Figure below), and, at the same time, the triceps muscle relaxes. The biceps is the flexor, and the triceps is the extensor of your elbow joint.
What type of reflex is the biceps reflex?
Unsourced material may be challenged and removed. Biceps reflex is a reflex test that examines the function of the C5 reflex arc and the C6 reflex arc. The test is performed by using a tendon hammer to quickly depress the biceps brachii tendon as it passes through the cubital fossa.
What nerve innervates the triceps?
the radial nerve
The medial head of the triceps brachii muscle was always innervated by the radial nerve (ulnar collateral branch). The branches seeming to leave the ulnar nerve at elbow level were the continuation of the radial nerve that had joined the ulnar nerve sheath via a connection in the axillary region.
What are the effectors of somatic reflexes?
In somatic reflexes, the effector is skeletal muscle. In autonomic (visceral) reflexes, the effector is smooth or cardiac muscle, or a gland.
When the flexor muscles of one arm contract in a withdrawal reflex the extensor muscles of the other arm contract What is this response called?
A & P
| Question | Answer |
|---|---|
| When the flexor muscles of one arm contract in a withdrawal reflex, the extensor muscles of the other arm contract. This phenomenon is called | crossed extensor flexion |
| If the right lateral spinothalamic tract is severed | pain impulses from the left side are blocked |
| All reflexes have | a reflex arc |
What nerve innervates the triceps muscle?
What Innervates the triceps?
Note: All the three heads of triceps brachii are innervated by the four branches of the radial nerve (C7, C8). However, according to the cadaveric study it is found that the medial head of triceps brachii is innervated by the ulnar nerve..
How does the biceps and triceps work together?
The biceps and triceps act against one another to bend and straighten the elbow joint. To bend the elbow, the biceps contracts and the triceps relaxes. To straighten the elbow, the triceps contract and the biceps relax.
How biceps and triceps produce movement?
When your biceps muscle in your upper arm contracts, it pulls your lower arm in towards your shoulder. However, when it relaxes, your biceps cannot push your arm back out. To do this, your triceps muscle, on the underside of your upper arm, contracts and straightens your arm out.
Which part of the reflex hammer will you use to test the biceps?
Which part of the reflex hammer can you use to test the biceps reflex? The pointed rubber side, the broad rubber side.
