Back of the head Anatomy

Back Of The Head Anatomy
FIG. 602– Superficial lymph glands and lymphatic vessels of head and neck.
The lymph glands of the head are arranged in the following groups:
Occipital. Facial.
Posterior Auricular. Deep Facial.
Anterior Auricular. Lingual.
Parotid. Retropharyngeal.
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. Their afferent vessels drain the occipital region of the scalp, while their efferents pass to the superior deep cervical glands.
The posterior auricular glands (lymphoglandulæ auriculares; mastoid glands), usually two in number, are situated on the mastoid insertion of the Sternocleidomastoideus, beneath the Auricularis posterior. Their afferent vessels drain the posterior part of the temporoparietal region, the upper part of the cranial surface of the auricula or pinna, and the back of the external acoustic meatus; their efferents pass to the superior deep cervical glands.
The anterior auricular glands (lymphoglandulæ auriculares anteriores; superficial parotid or preauricular glands), from one to three in number, lie immediately in front of the tragus. Their afferents drain the lateral surface of the auricula and the skin of the adjacent part of the temporal region; their efferents pass to the superior deep cervical glands.
The parotid glands (lymphoglandulæ parotideæ), form two groups in relation with the parotid salivary gland, viz., a group imbedded in the substance of the gland, and a group of subparotid glands lying on the lateral wall of the pharynx. Occasionally small glands are found in the subcutaneous tissue over the parotid gland. Their afferent vessels drain the root of the nose, the eyelids, the frontotemporal region, the external acoustic meatus and the tympanic cavity, possibly also the posterior parts of the palate and the floor of the nasal cavity. The efferents of these glands pass to the superior deep cervical glands. The afferents of the subparotid glands drain the nasal part of the pharynx and the posterior parts of the nasal cavities; their efferents pass to the superior deep cervical glands.
