Which structure is found in the 'Superior orbital fissure'?

optic nerve and opthalmic artery

What is the primary function of the 'Ciliary body' in the eye?

A patient sustained an injury to a nerve and no longer has the ability to look to the left with their left eye. Which nerve is most likely to be injured?

Abducens

True or false: the parotid gland is the largest salivary gland AND produces the greatest amount of saliva in your oral cavity.

FALSE,  it is the largest but the submandibular gland produces more

True or false: the lateral pterygoid muscle elevates the mandible

FALSE, the medial pterygoid elevates. The lateral is the only muscle of mastication to open the mouth.

membrane?

Malleus

Sensory innervation to the External ear is supplied by both cranial and spinal nerves.

True

The External ear receives its blood supply from branches off the Internal Carotid artery.

Of the 4 TMJ muscles discussed in lecture, which one(s) are MOST involved with jaw elevation

(closing)?

Masseter and Temporalis

At the beginning motions of jaw depression (opening) and return to neutral position from

depression (elevation), (the initial ~15-20deg) the MAIN motion of the TMJ is:

Rotation motion of the convex mandibular condyle on the concave disc

The Mandibular nerve, also known as the V3 division of the Trigeminal nerve, is the largest of

the three branches (V1, V2,and V3) and is responsible for BOTH sensory and motor functions in

the lower face and jaw.

True

The 3 Scalene muscles originate from the transverse processes of the cervical spine and insert

onto the ipsilateral 1 st and 2 nd ribs, so they assist with deep respiration as well as laterally flex the

neck to the ipsilateral (same) side.

true

The 4 deep neck flexor muscles group sit directly against the anterior portion of the cervical

vertebrae, beneath the larger, superficial muscles (like the sternocleidomastoid (SCM)) and

together their MAIN function is:

Executing the subtle "nodding" or “yes” motion of the head via the upper cervical segments

(C0-C1)
