What myotome is shoulder flexion?

Myotome distributions of the upper and lower extremity are as follows; C1/C2: neck flexion/extension. C3: Lateral Neck Flexion. C4: shoulder elevation.

What Myotomes are responsible for Plantarflexion of the foot?

L5 – Great toe extension. S1 – Ankle plantarflexion.

What is the L1 myotome?

The lumbar and sacral myotomes (L1-S3) are tested with the patient lying supine. These are tested with movements of the hip, knee, ankle, intertarsal, and metatarsophalangeal joints. Movements for lumbar and sacral myotome testing. L1-L3. Flexion and medial (internal) rotation of the thigh at the hip joint.

Which is myotome is associated with elbow flexion?

For example, the biceps brachiimuscle flexes the elbow. It is innervated by the musculocutaneousnerve, which is innervated by C5, C6 and C7 nerve roots. All three of these spinal nerve roots can be said to be associated with elbow flexion. The list below details which movement(s) has the strongest association with each myotome:

Which is an example of a muscle composed of multiple myotomes?

Most muscles in the upper and lower limbs receive innervation from more than one spinal nerve root. They are therefore comprised of multiple myotomes. For example, the biceps brachii muscle performs flexion at the elbow.

How are myotomes distributed in the human body?

Distribution of Myotomes. Most muscles in the upper and lower limbs receive innervation from more than one spinal nerve root. They are therefore comprised of multiple myotomes. For example, the biceps brachii muscle performs flexion at the elbow. It is innervated by the musculocutaneous nerve, which is derived from C5, C6 and C7 nerve roots.

Which is movement has the strongest association with Each myotome?

It is innervated by the musculocutaneous nerve, which is innervated by C5, C6 and C7 nerve roots. All three of these spinal nerve roots can be said to be associated with elbow flexion. The list below details which movement (s) has the strongest association with each myotome: C5- shoulder abduction
