Branchiomeric Muscles are striated muscles of the head and neck. Unlike skeletal muscles that developmentally come from somites, branchiomeric muscles are developmentally formed from the branchial arches. Structure of a skeletal muscle Skeletal muscle is a type of striated muscle, attached to the skeleton. ...

In the developing vertebrate embryo, somites are masses of mesoderm distributed along the two sides of the neural tube and that will eventually become dermis, skeletal muscle and vertebrae. ...
In the development of vertebrate animals, the branchial arches (or pharyngeal arches) develop during the fourth and fifth week in utero as a series of mesodermal outpouchings on the left and right sides of the developing pharynx. ...
Branchiomeric muscles from each Branchial Arch
First Arch All of the branchiomeric muscles that come from the first branchial arch are innervated by the trigeminal nerve. These muscles inclulde all the muscles of mastication (temporalis, masseter, lateral pterygoid, and medial pterygoid), the anterior belly of the digastric, the mylohyoid, tensor tympani, and tensor veli palatini. The trigeminal nerve is the fifth (V) cranial nerve, and carries sensory information from most of the face, as well as motor supply to the muscles of mastication (the muscles enabling chewing), tensor tympani (in the middle ear), and other muscles in the floor of the mouth, such as the...
Mastication is a name for the process of breaking up of food and mixing it with saliva. ...
The temporalis muscle is one of the muscles of mastication. ...
In human anatomy, the masseter is one of the muscles of mastication. ...
The lateral pterygoid (or external pterygoid) is a muscle of mastication with two heads. ...
Medial pterygoid can refer to: Medial pterygoid muscle Medial pterygoid plate Category: ...
The Digastric is a muscle of the human body. ...
Mylohyoid can refer to: Mylohyoid muscle Mylohyoid line This is a disambiguation page: a list of articles associated with the same title. ...
The tensor tympani muscle arises from the auditory tube and inserts onto the handle of the malleus, damping down vibration in the ossicles and so reducing the amplitude of sounds. ...
The Tensor veli palatini muscle (or Tensor palati) is a muscle of the human body. ...
Second Arch All of the branchiomeric muscles of the second brachial arch are innervated by the facial nerve. These muscles include the muscles of facial expression, the posterior belly of the digastric, stylohyoid muscle, and the stapedius muscle of the middle ear. The facial nerve is seventh of twelve paired cranial nerves. ...

The Stylohyoid muscle is a slender muscle, lying in front of, and above the posterior belly of the digastric muscle. ...
The stapedius is the smallest striated muscle in the human body. ...
Third Arch There is only one muscle of third brancial arch, the stylopharyngeus. The stylopharyngeus and other structures from the third brachial arch are all innervated by the glossopharyngeal nerve. The Stylopharyngeus muscle is a muscle of the human body. ...
The glossopharyngeal nerve is the ninth of twelve cranial nerves. ...
Fourth Arch All the brachial muscles of the fourth arch are innervated by the vagus nerve. These muscles include all the muscles of the palate (exception of the tensor veli palatini which is innervated by the trigeminal nerve), all the muscles of the pharynx (except stylopharyngeus which is innervated by the glossopharyngeal nerve, and all the muscles of the larynx. The vagus nerve (also called pneumogastric nerve or cranial nerve X) is the tenth of twelve paired cranial nerves, and is the only nerve that starts in the brainstem (within the medulla oblongata) and extends, through the jugular foramen, down below the head, to the abdomen. ...
