ganglion
m.in the parotid bed
腮腺床
Ⅺ
Carotid sheath,and n. in parotid bed
The superficial structures of face
(P 348-354)
• 1. The skin: 1) There are rich
sebaceous glands (皮脂腺), sweat glands, hair follicles(毛囊), and blood supplying. 2) It is thin and rich elasticity.
Anastomosis occurs between branches of the left and right facial aa..
(2) facial vein
begins at the angular v. at the medial angle of the eye;
Parotid Area
(P 394)
Parotid gland P.394
1) the largest one of the 3 paired salivary glands
2) enclosed within the fascia parotid sheath formed by enveloping fascia superficial part of the sheath is the thicker and gives off the many fibrous septa into the gland. deep part of the sheath is the thinner.
5) Structures within the gland
(1) Longitudinal structures external carotid a. superficial temporal v.and a. retromandibular v. auriculotemporal n.
(2) Transverse maxillary a. and v. transverse facial a. and v. br. of the facial n. parotid duct
2) The facial vessels
(1) Facial artery
arises from external carotid a.;
runs upwards and forwards;
turns around the lower border of mandible crossing with anterior border of the masseter;
Parotid gland P.394
3) position and division: * It lies on the lateral side of the face
and anteroinferior to the external acoustic meatus
*posterior border of masseter *in the retromandibular fossa
deep isthmus
Superficial part of
4) Parotid duct 腮腺导管
It passes horizontally from the anterior edge of the gland, runs forwards at the surface of the masseter, inferior to the zygomatic arch. At the anterior border of the masseter, the duct turns medially, pierces buccinator, and opens on a small papilla on the buccal mucosa of oral surface of the cheek opposite the second maxillary molar tooth.

2. Superficial fascia 1) loose connective tissue:
*corpusadiposum buccae(颊脂体) at the buccal part
* at the palpebra(睑), subcutaneous fat is lesser and looser.
下颌后窝
division of parotid gland
superficial part: superficial to the posterior part of masseter
deep part: in the retomandibular fossa isthmus: face to the ramus of mandible
blood vessels and auriculotemporal n.
Parotid –bed A lot of m.attached to the styloid Carotid sheath Lower 4 paired cranial n. Superior cervical sympathetic
6) The main structures leaving the edge of the parotid gland
Temporal br. Zygomatic br. Buccal br. Mandibular br. Cervical br. Parotid duct Superficial temporal
enters the face where the facial a.runs lateral to the angle of the mouth and wing of nose, and then
reaches the medial canthus(内眦), where it becomes the angular a.;
