size. When they are present they lie in association with the anterior jugular veins. 

 The exact origin of their afferents and the terminations of their efferents are 

 unknown, but it is probable that they receive lymph from the superficial tissues of 

 the anterior parts of the neck, and transmit it to the lower deep cervical glands. 



The deep anterior cervical lymph glands are 



(a) Infra-hyoid glands, which lie anterior to the hyo-thyreoid membrane. 

 They receive lymph from the region of the epiglottis and transmit it to the deep 

 cervical glands. They are not constantly present. 



(&) The prelaryngeal gland, which lies either anterior to the cricoid cartilage 

 or to the crico-thyreoid ligament. Its occurrence is very constant. It receives

iph from the anterior part of the larynx and from the isthmus and the adjacent 

 of the right and left lobes of the thyreoid gland. Its efferents terminate 

 in the deep cervical and the pretracheal glands. 



(c) The pretracheal lymph glands are numerous small nodules which lie along 

 the inferior thyreoid veins. They receive lymph from the trachea, the lower part of 

 the larynx, and from the lobes and the isthmus of the thyreoid gland ; and they 

 transmit it to the lower deep cervical glands. 



(d) The paratracheal lymph glands lie along the sulcus between the larynx and 

 the trachea, anteriorly, and the pharynx and oesophagus, posteriorly, in association 

 with the branches of the superior and inferior thyreoid arteries and the recurrent 

 nerves. They receive lymph from the adjacent parts and transmit it to the deep 

 cervical glands (Fig. 800).
