What are the neck extensors?
The neck extensors are the group of muscles located on the back of the neck that help to extend (tilt backward) the head and neck. These muscles include the splenius capitis, semispinalis capitis, and the upper portion of the trapezius. Strengthening these muscles can help improve posture and reduce neck pain.
What muscles are attached to the temporal bone?
The temporal bone is the attachment point for the temporalis muscle, which is one of the primary muscles involved in chewing. Additionally, the sternocleidomastoid muscle, which is involved in neck movement, attaches to the temporal bone near the mastoid process.
What are the muscles attached to spine of sphenoid?
The muscles attached to the spine of the sphenoid bone include the rectus capitis posterior minor, rectus capitis posterior major, and obliquus capitis inferior. These muscles are involved in head and neck movement and stability.
What is the extension of the head?
The extension of the head refers to the action of tilting the head backwards, usually to look up towards the ceiling or sky. This movement is controlled by the muscles at the back of the neck and is important for maintaining good posture and range of motion in the neck.
Which bone supports the larynx superiorly?
The hyoid bone supports the larynx superiorly. It is a U-shaped bone located in the neck and serves as a point of attachment for muscles involved in swallowing and speech.
Which parts of the body involved in speaking?
Respiratory muscles means thorax, laryngeal muscles means neck, ears and brain are involved in phonation or speaking.
Identify the three categories of head and neck muscles?
The three categories of head and neck muscles are the facial muscles, which control expressions; the muscles of mastication, which are involved in chewing; and the neck muscles, which facilitate movements such as bending and rotation of the head. Facial muscles include groups like the orbicularis oris and zygomaticus. The muscles of mastication primarily include the masseter and temporalis. Neck muscles encompass the sternocleidomastoid and trapezius, among others.
What type of muscle is associated with the neck?
Yes. One major group of neck muscles supports and provides movement for the head. Other groups of muscles in the neck and shoulders allow movement of the arms. The neck muscles also coordinate with the muscles of the jaw.
What is The primary muscles involved in torticollis?
The primary muscles involved in torticollis are the sternocleidomastoid muscles, which are located on either side of the neck. When one of these muscles is contracted or shortened, it can cause the head to tilt to one side and rotate to the opposite side. Other muscles that may be affected include the trapezius and splenius capitis, which can also contribute to neck movement and positioning in individuals with torticollis.
What are the 2 main muscles in the neck?
The two main muscles in the neck are the sternocleidomastoid and the trapezius. The sternocleidomastoid, located on each side of the neck, is responsible for rotating and flexing the head. The trapezius, which extends from the back of the skull to the middle of the back, helps in moving, rotating, and stabilizing the shoulder blades and extends the neck. Together, these muscles play crucial roles in neck movement and stability.
Which muscles move when you nod your head?
When you nod your head, the muscles that are primarily involved are the sternocleidomastoid and the longus colli muscles. These muscles work together to flex the neck and tilt the head forward.
How did your head swing?

What muscles do you use when turning head from side to side?
When turning your head from side to side, the primary muscles involved are the sternocleidomastoid muscles, which are located on either side of the neck. These muscles contract to rotate the head and flex the neck. Additionally, the splenius capitis and splenius cervicis muscles assist in the movement by providing support and stabilization. Other muscles, such as the trapezius and the levator scapulae, also contribute to neck rotation and stability.
The primary muscles involved in torticollis are?
The primary muscles involved in torticollis are the sternocleidomastoid muscle and the trapezius muscle. These muscles are responsible for controlling the position and movement of the head and neck. Injury or spasm of these muscles can cause the characteristic head tilt and rotation seen in torticollis.
Which of the cervical muscles can be palpated in the neck?
the two muscles of the neck are both superficial and are easy palpated in the neck those cervical muscles are STERNOCLEIDOMASTIOD AND TRAPEZIUS
What cranial nerve is involved in hyper extending and flexing the neck?
The spinal accessory nerve (cranial nerve XI) is involved in hyperextending and flexing the neck. This nerve innervates the trapezius and sternocleidomastoid muscles, which are involved in these movements.
What body systems are involved when you hit your head on the top of the car as you get into it?
Mainly the head but also the neck muscles which support the head.
