Lymphatic's of Head & Neck Flashcards
What are the major lymph node groups of the neck?
pericervical collar x2
superficial cervical group x2
intermediate (anterior deep) cervical group x2
deep cervical group (superior & inferior) x2
What are the pericervical lymph nodes?
occipital mastoid/ retroauricular parotid/ preauricular submandibular submental
Where are the occipital lymph nodes located?
a few small lymph nodes lies on the superior end of the trapezius muscle
Where do all of the lymphatic vessels from the head and neck drain into?
deep cervical lymph nodes
What do the afferent vessels of the occipital lymph nodes drain from?
the occipital part of the scalp and superior part of the neck
Where do the efferent vessels of the occipital lymph nodes drain into?
drain to the superficial cervical nodes along the external jugular vein before draining into the deep cervical lymph nodes
Where are the mastoid/ retroauricular lymph nodes located?
a few small lymph nodes lie on the superior part of the sternocleidomastoid muscle, posterior to the auricle
What do the afferent vessels of the mastoid/ retroauricular lymph nodes drain from?
drain the posterior half of the lateral aspect of the scalp and the posterior surface of the auricle
Where do the efferent vessels of the mastoid/ retroauricular lymph nodes drain into?
drain to the superficial cervical nodes along the external jugular vein before draining into the deep cervical lymph nodes
What are the parotid/ prauricular lymph nodes?
numerous small lymph nodes are closely related to the parotid gland, superficial, within the gland and deep; receive lymph from the superficial and deep parts of the head
Where do the afferent vessels of the parotid/ prauricular lymph nodes drain from?
the afferents of the usperficial lymph nodes drain the anterior half of the face and scalp
the affernet vessels of the deep lymph nodes drain the temporal and infratemporal fossae, the middle ear, auditory tube and maxillary molar teeth and gingivae
Where do the efferent vessels of the parotid/ prauricular lymph nodes drain into?
efferent vessels of the parotid lymph nodes drain to the deep cervical lymph nodes
