Anatomy Of The Head And Neck Glands

The endocrine system is the system of glands each of which secretes different types of hormones directly into the bloodstream some of which are transported along nerve tracts to regulate the body. Superior thyroid mostly supplies the neck ascending pharyngeal lingual facial occipital posterior auricular and maxillary arteries.

The thyroid gland is a butterfly shaped endocrine gland placed anteriorly to the thyroid cartilage of the larynx.

Anatomy of the head and neck glands. The major paired salivary glands which includes the parotid submandibular and sublingual glands and the minor salivary glands which line the mucosa of the upper aerodigestive tract and the overwhelming entirety of the mouth. Left and right like the wings of the butterfly. They glands are divided into two main types.

Epidermis dermis and hypodermis. Endocrine glands in the human head and neck. The lacrimal glands are serous type exocrine glands that secrete lacrimal fluid onto the surfaces of the conjunctiva and cornea of the eye.

The most important ones for head anatomy branch from the external carotid arteries. The parotid is the largest of the three glands and is bordered superiorly by the zygomatic arch anteriorly and medially by the masseter and posteriorly by the sternocleidomastoid. The parotid gland along with the submandibular and sublingual glands is one of the three paired major salivary glands.

The lobes are connected by an isthmus the body of the butterfly. Anatomy of the head neck paired organs include the tonsils parotid glands other major salivary glands maxillary and frontal sinuses and the nasal cavities. The occipital glands lymphoglandulæ occipitales one to three in nu ber are placed on the back of the head close to the margin of the trapezius and resting on the insertion of the semispinalis capitis.

Specific sub sites of these organs which are considered lateral sites are indicated with an asterisk in the code table above. The lymph glands of the head are arranged in the following groups. They ultimately drain into the deep lymph nodes.

The head and neck is covered in skin and its appendages termed the integumentary system. The skin is made up of three microscopic layers. Extending from underneath the chin to the posterior aspect of the head.

There are usually between 1 3 occipital lymph nodes. Basic thyroid anatomy describes the gland as having two lobes. These include hair sweat glands sebaceous glands and sensory nerves.

The superficial lymph nodes of the head and neck receive lymph from the scalp face and neck. They are arranged in a ring shape.
