Mastering Neck Muscles and Movements

The video tutorial discusses the muscles that move the neck, focusing on neck flexion and extension. It explains the roles of the sternocleidomastoid and scalene muscles in flexion, and the trapezius, splenius capitis, and semispinalis capitis in extension. The video also touches on muscles like the levator scapulae, which do not move the neck, and briefly mentions the hyoid muscles.

Which muscle is primarily responsible for neck flexion?

• Trapezius

• Sternocleidomastoid

• Levator scapulae

• Splenius capitis

What is the function of the scalene muscles?

• Elevate the scapula

• Flex the neck

• Rotate the head

• Extend the neck

What happens when the neck muscles are flexed unilaterally?

• The shoulders shrug

• The head bends laterally

• The neck extends

• The head rotates

Which muscle elevates the scapula?

• Semispinalis capitis

• Levator scapulae

• Splenius capitis

• Sternocleidomastoid

Which muscle is not involved in moving the neck but is mentioned in the context of neck muscles?

Which muscle is located over the semispinalis capitis?

• Levator scapulae

• Sternocleidomastoid

• Splenius capitis

• Trapezius

What is the primary function of the trapezius muscle in the context of neck movement?

• Elevate the scapula

• Flex the neck

• Extend the neck

• Rotate the head

Which muscle is described as having a superior and inferior belly?

• Sternocleidomastoid

• Trapezius

What does 'omo' refer to in the context of the omohyoid muscle?

• Chest

• Head

• Shoulder
