Final week Flashcards
What forms the ventral slip of the intertransverse ligament in the lumbar spine?

the nasion, vertex, inion and gnathion
What is unique about the ophthalmic artery and vein?
Unlike other artey-vein combinations they will not share the same opening the ophthalmic artey is in the optic canal, ophthalmic veins are in the superior orbital fissure.
What are the contents of the foramen spinosum?
the nervus spinosus from the mandibular division of the trigeminal nerve and the middle meningeal artery.
What forms the roof of the posterior cranial fossa?
the tentorium cerebelli.

Skin, Connective tissue, Aponeurosis, Loose Connective Tissue, Periosteum..SCALP
What are the major constituents of the five layers of the scalp?
Skin, neurovascular, muscular, loose connective tissue, periosteum.
Which muscles lack any attachment to bone?
orbicularis oris, procerus and risorius
What is the name given to the medial wall of the orbit?
lamina papyracea.
Identify the opening(s) found along each wall of the orbit?
superior wall:optic canal
medial wall:anterior ethmoid and posterior ethmoid foramina
lateral wall:superior orbital fissure
inferior wall:inferior orbital fissure
What are the names given to the modified sebaceous glands of the palpebra?
The tarsal gland or Meibomian gland and ciliary gland.
What are the parts of the uveal tract of the eyeball?
iris,ciliary body, choroid and pupil
What is contained in the posterior chamber of the eyeball?
Aqueous Humor
What fills the vitreous chamber?
Vitreous body
What is the common characteristic concerning the insertion of the superior and inferior rectus extraocular eye muscles?
They insert onto the sclera of the eyeball in front of the equator and are displaced slightly medially.
What is the common characteristic regarding the insertion of both oblique extraocular eye muscles?
both insert onto the sclera on the lateral margin of the eyeball behind the equator
What is the name of the palpable posterior projection of the eminentia concha of the auricle?
Ponticulus
Skin lining the external acoustic meatus contains what modified sebaceous glands?
ceruminous glands
What branch of the facial nerve penetrates the parotid gland, but is not given off within it?
The chorda tympani nerve
Describe the result of sympathetic innervation in the parotid gland.
vasoconstriction of arteries reduces available water to form saliva and results in a thick, mucous-like product.
What action will parasympathetic innervation have on the parotid gland?
vasodilation of arteries resulting in a thinner, watery, or whey-like saliva.
The otic ganglion will be located in which region of the head?
the infratemporal region
What are the attachment sites of the lateral/temporalmandibular ligament?
zygomatic process and articular tubercle of the temporal bone to neck of the mandible
What are the attachment sites of the stylomandibular ligament?
styloid process of the temporal bone to the angle of the mandible
What are the attachment sites to the sphenomandibular ligament?
the spine of the sphenoid bone to the lingula of the mandible
