Structure | Location/Description | Notes |
---|---|---|
fascia, alar | anterior lamina of the prevertebral fascia, attaching anteriorly to visceral fascia behind esophagus in the superior thorax | alar fascia separates the retropharyngeal space above from the posterior mediastinum below |
fascia, buccopharyngeal | posterior part of the visceral fascia of the neck | buccopharyngeal fascia lies behind the pharynx and esophagus |
bulbar sheath | fascia that invests the entire eyeball except for the cornea | bulbar sheath separates the eyeball from the surrounding orbital structures (fat, etc.); it is fused with the sheath of the optic nerve posteriorly, and it is penetrated by the tendons of the extraocular mm. |
fascia, infrahyoid | deep fascia covering the infrahyoid muscles | infrahyoid fascia is composed of two layers: a superficial layer associated with the sternohyoid and omohyoid mm. and a deep layer associated with the sterhothyroid and thyrohoid mm. |
fascia, masseteric | fascia surrounding the masseter m. | masseteric fascia attaches to the zygomatic arch superiorly and to the mandible inferiorly |
fascia, palpebral | part of the orbital septum within the eyelid | superior and inferior palpebral fasciae can be identified; these are subunits of the orbital septum; the superior palpebral fascia is penetrated by the tendon of the levator palpebrae superioris m. |
fascia, parotid | fascia surrounding the parotid gland | parotid fascia is an extension onto the face of the superficial layer of deep cervical fascia; it is very dense, extends into the parotid gland and is very difficult to dissect |
fascia, pharyngobasilar | submucosa of the pharynx | pharyngobasilar fascia is attached to the base of skull and is best seen above the superior edge of the superior pharyngeal constrictor m. |
fascia, pretracheal | anterior part of the visceral fascia of the neck | pretracheal fascia covers the larynx,/trachea and thyroid gland |
fascia, prevertebral | deep fascia surrounding vertebral column and associated muscles | prevertebral fascia covers the scalene mm. where it is called scalene fascia |
fascia, pterygoid | fascia that surrounds the pterygoid mm. | pterygoid fascia attaches to the pterygoid plates |
fascia, scalene | part of the prevertebral fascia covering the scalene mm. | reinforces the cervical pleura (known there as Sibson's fascia) and extends out onto the ventral primary rami of spinal nn. C5-T1 as the axillary fascia |
fascia, superficial layer of deep cervical | deep fascia investing all of the deep neck structures | superficial layer of deep cervical fascia extends between the trapezius m. and sternocleidomastoid m.. in the posterior cervical triangle and between the paired sternocleidomastoid mm. in the anterior cervical triangle |
fascia, temporal | a strong aponeurotic sheet of fascia that covers the superficial surface of the temporalis m. | temporal fascia is an origin for the temporalis m.; it attaches to the bones of the skull superiorly and to the zygomatic arch inferiorly |
fascia, visceral | deep fascia enclosing the visceral structures of the neck (thyroid gland, larynx, trachea, esophagus) | the anterior part is also known as pretracheal fascia; the posterior part also known as buccopharyngeal fascia |
orbital septum | a plane of connective tissue that separates the superficial part of the eyelid from the orbit | orbital septum attaches to the periosteum at the margins of the orbit; orbital septum and tarsal plate form a complete layer posterior to the orbicularis oculi m. that prevents blood and fluids from passing superficially or deeply across the eyelid; blunt trauma to the forehead and scalp may result in blood pooling in the superficial part of the eyelid because of this septum |
periorbita | fascia that lines the orbit | periorbita is the periosteum of the orbit; it is loosely attached to the bones of the orbit and is easily dissected from them |
