Answer 1

The specific groups within the muscles of the head and neck include muscles of facial expression, extrinsic eye muscles, muscles of mastication, muscles that move the tongue, muscles of the pharynx, and muscles of the anterior neck.

Step-by-step explanation:

The specific groups within the muscles of the head and neck include:

1. Muscles of facial expression: These muscles, such as the orbicularis oris and frontalis, are responsible for producing various facial expressions.
2. Extrinsic eye muscles: These muscles, such as the rectus and oblique muscles, move the eyeballs in different directions.
3. Muscles of mastication: These muscles, such as the masseter and temporalis, are involved in chewing and jaw movements.
4. Muscles that move the tongue: These muscles, including the genioglossus and styloglossus, control the movements of the tongue.
5. Muscles of the pharynx: These muscles, such as the pharyngeal constrictors, aid in swallowing and speech.
6. Muscles of the anterior neck: These muscles, including the suprahyoid and infrahyoid muscles, play a role in swallowing and stabilizing the larynx.
