Which of the following is the prime mover of neck flexion?
The prime mover of neck flexion is the d) sternocleidomastoid.
What is the prime mover in head flexion?
The prime movers of head/neck flexion are: the sternocleidomastoid, anterior scalene, longus capitis, and the longus colli.
What are the prime movers of the hand?
Muscles include: Flexor Carpi Ulnaris (prime mover), Flexor Carpi Radialis (prime mover), Palmaris longus (tightens the skin and fascia in the palm), Flexor Digitorum Superficialis (finger flexor, assists only).
What are the 3 prime movers for the ankle joint?
The medial leg muscles, anterior tibialis and posterior tibialis, are the prime movers responsible for inversion of the foot.
What muscles are involved in neck flexion?
The scalene muscles help with neck flexion and side bending. The deep cervical flexors are a muscle group consisting of the longus capitus and longus colli muscles, which run down the front of the cervical spine. The deep cervical flexor muscles help flex the neck forward as well as stabilize the cervical spine.
Which of the following is a prime mover in head flexion quizlet?
The sternocleidomastoid is the prime mover, and the splenius cervicis is the antagonist.
What is the prime mover of head extension?
The semispinalis cervicis and semispinalis capitis These muscles originate on the upper thoracic vertebrae and insert high on the cervical vertebrae and occipital bone. When both sides act together, they are prime movers for extension-hyperextension of the head and cervical spine.
What muscles flex the hand?
The six muscles are the flex carpal radialis muscle, the flexor carpal ulnaris muscle, the flexor pollicis longus muscle, the flexor digitorum profundus muscle, the flexor digitorum superficialis muscle, and the palmaris longus muscle.
What is the agonist in wrist flexion?
Agonists: Extensor Carpi Radialis Longus, Flexor Carpi Radialis, Abductor Pollicis Longus. Antagonists: : Extensor Carpi Ulnaris, Flexor Carpi Ulnaris.
What is the prime mover of inversion of the foot?

| Term tibialis anterior | Definition prime mover of dorsiflexion of the foot |
What muscle is the prime mover of inversion of the foot?
Tibialis posterior: The tibialis posterior is a smaller muscle that lies deep in the lower leg. It’s involved with both plantar flexion and inversion — when you turn the sole of the foot inward toward the other foot.
What muscles control shoulder flexion?
The muscles involved in the flexion movement include the anterior deltoid, pectoralis major and coracobrachialis. For a shoulder extension, your body uses the latissimus dorsi, teres major and minor and posterior deltoid muscles.

|---|---|---|
| Sternocleidomastoid | Extends & rotates head, flexes vertebral column | C2, C3 |
| Scalenus | Flexes & rotates neck | Lower cervical |
| Spinalis Cervicis | Extends & rotates head | Middle/lower cervical |
| Spinalis Capitus | Extends & rotates head | Middle/lower cervical |
Which muscle extends and laterally flexes the neck?
Splenius capitis: extension of head/neck by bilateral contraction, lateral flexion and rotation of the head (ipsilateral) by unilateral contraction.

Which of the following is a prime mover in the neck extension?
Being large and superficial, the trapezius covers many deeper muscles. Although the muscle is largely categorized as a prime mover of the shoulder and upper arm, its attachments to the skull and cervical vertebrae make it a prime mover in cervical extension, lateral flexion, and rotation as well.
Which muscle is responsible for flexing the neck?
scalene muscles
The scalene muscles help with neck flexion and side bending. The deep cervical flexors are a muscle group consisting of the longus capitus and longus colli muscles, which run down the front of the cervical spine. The deep cervical flexor muscles help flex the neck forward as well as stabilize the cervical spine.
What is hand flexion?
Wrist flexion is the action of bending your hand down at the wrist, so that your palm faces in toward your arm. It’s part of the normal range of motion of your wrist. When your wrist flexion is normal, that means that the muscles, bones, and tendons that make up your wrist are working as they should.
What is the range of motion of thumb MCP joint?
Flexion in the third to the fifth MCP joint is accompanied by a slight lateral rotation, while the flexion that occurs in the second MCP joint is accompanied by a slight medial rotation. The full range of motion for the thumb MCP joint is about 60° which is almost completely flexion.
What muscles are involved in the movement of the MCP joints?
All the movements of the MCP joints are performed by the muscles of the forearm and hand. Flexion of the thumb is mainly produced by flexor pollicis brevis, aided by flexor pollicis longus muscle.
