Eyelids (A– C)

The eyeball is embedded in the orbit and is covered by the eyelids. The upper eyelid (A1) and the lower eyelid (A2) demarcate the palpebral fissure. The latter ends in the medial angle of the eye (A3) with a recess enclosing the lacrimal caruncle (A4).

 What Does The Spinal Cord Do?

The spinal cord actually is part of the brain and plays a major role. Scientists have known for the past 100 years or so that the spinal cord is actually part of the brain. According to Melillo, while the brain has grey matter on the outside (protected by the skull) and protected white matter on the inside, the spinal cord is the reverse: the grey matter is inside the spinal cord and the white matter is outside.

Parotid Gland Anatomy

Parotid Gland Anatomy

pediagenosis    January 27, 2023    Comment   

Parotid Gland

The parotid is the largest of the salivary glands and is pyramidal in shape (Fig. 7.25). Its base faces laterally between the anterior border of sternocleidomastoid and the ramus of the mandible, while its apex lies deeply against the styloid process. The gland extends upwards between the external acoustic meatus and the temporomandibular joint, movements of which may be painful when the parotid is inflamed.

Superficial Structures of the Face and Scalp

The subcutaneous tissue of the face and scalp is highly vascular and is traversed by several nerves. Most of the nerves are sensory to skin and include branches of the trigeminal (V) and upper cervical spinal nerves. In addition, there are branches that are motor from the facial (VII) nerve to a group of muscles in the subcutaneous tissues of the face, scalp and front of the neck, known as the muscles of facial expression.

Neck Anatomy

Fascial layers

These are complex and are divided into four components: investing fascia, prevertebral fascia, pretracheal fascia and carotid sheaths (Fig. 7.5). The investing fascia is analogous to deep fascia in the limbs. Deep to the skin and superficial tissues, it surrounds the neck, extending from the pectoral girdle below to the base of the skull and mandible above, and splits to enclose trapezius and sternocleidomastoid. Superiorly, the investing fascia is attached to the superior nuchal lines and to the mastoid processes. Between the mastoid process and the angle of the mandible the fascia encloses the parotid gland. Its superficial layer passes superiorly over the surface of the gland to attach to the zygomatic arch; on its deep surface the fascia is thickened to form the stylomandibular ligament. Inferiorly, the investing fascia is attached to the spine of the scapula, the acromion, the superior border of the clavicle, and the manubrium.

Masseter, Temporalis and Infratemporal Fossa

Masseter

Masseter (Fig. 7.29) attaches along the length of the zygomatic arch and its fibres slope downwards and backwards to the lateral surface of the ramus of the mandible adjacent to the angle (Fig. 7.31). This muscle is a powerful elevator of the mandible and is easily palpated when the teeth are clenched. It is supplied by the masseteric branch of the mandibular (V3) division of the trigeminal nerve.
