The human face is composed of numerous muscles that control fine movement to produce facial expressions. Unlike other muscles, these muscles originate on bone or fascia of the face and attach directly to the skin, allowing it to be manipulated. Jul 06, · The muscles of the face overlap and crisscross over each other, creating a mask of muscle over the skull and jawbone. They attach to various parts of .
Jul 16, · The neck muscles, including the sternocleidomastoid and the trapezius, are responsible for the gross motor movement in the muscular system of the head and neck. They move the head in every direction, pulling the skull and jaw towards the shoulders, spine, and scapula. The skull has various functions including protection of brain, support of the facial muscles by providing origin and insertion sites, development of foramen to provide entry and exit places for the vasculature and nervous system and a defense function.

The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault (Figure ). The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws. Jul 24, · Occipitofrontalis Muscle of Face: The Occipitofrontalis muscle is also known as the Epicranius muscle and it covers some parts of the skulls. Located near the occipital bone and frontal belly, as well as occipital belly, this facial muscle helps in facial expression. #
The brain is encased in the cranium of the skull. The bones that make up the cranium are called the cranial bones. The remainder of the bones in the skull are the facial bones. Figure and Figure show all the bones of the skull, as they appear from the outside. The origins of the muscles of facial expression are on the surface of the skull (remember, the origin of a muscle does not move). The insertions of these muscles have fibers intertwined with connective tissue and the dermis of the skin.
Aug 29, · The facial muscles, also called craniofacial muscles, are a group of about 20 flat skeletal muscles lying underneath the skin of the face and scalp. Most of them originate from the bones or fibrous structures of the skull and radiate to insert on the skin .
