Choroid
|
- a dark reddish brown layer between the sclera and retina, forms the largest part of the vascular layer of the eyeball and lines most the sclera
|
|
|
Cornea
|
is the transparent part of the fibrous layer covering the anterior one/sixth of the eyeball
|
|
|
What are the 3 layers of the eyeball?
|
fibrous layer, vascular layer, inner layer
|
|
|
Levator palpebrae superioris
|
O: lesser wing of sphenoid bone
I: superior eyelid N: oculomotor nerve A: elevates superior eyelid |
|
|
Superior oblique
|
O: body of sphenoid
I: tendon passes through trochlea; inserts into sclera N: Trochlear nerve A: abducts, depresses, and medially rotates eyeball |
|
|
Inferior oblique
|
O: anterior part of floor of orbit
I: sclera deep to lateral rectus muscle N: Oculomotor nerve A: abducts, elevates, and laterally rotates eyeball |
|
|
Superior rectus
|
O: common tendinous ring
I: sclera N: oculomotor nerve A: elevates, adducts, and rotates eyeball medially |
|
|
Inferior rectus
|
O: common tendinous ring
I: sclera N: oculomotor nerve A: depresses, adducts, and rotates eyeball laterally |
|
|
Medial rectus
|
O: common tendinous ring
I: sclera N: oculomotor nerve A: adducts eyeball |
|
|
lateral rectus
|
O: common tendinous ring
I: sclera N: oculomotor nerve A: abducts eyeball |
|
|
Anterior- Posterior axis
|
lateral-medial rotation
|
|
|
Transverse axis
|
elevation-depression
|
|
|
vertical axis
|
abduction-adduction
|
|
|
Temporalis
|
O: temporal fossa
I: coronoid process N: mandibular nerve A: elevates mandible, closing jaws; posterior, more horizontal fibers are primary retractors of mandible |
|
|
Masseter
|
O: maxillary process of zygomatic bone and the zygomatic arch
I: angle and lateral surface of ramus of mandible N: mandibular nerve A: elevates mandible, closing jaws; superficial fibers make limited contribution to protrusion of mandible |
|
|
Medial pterygoid
|
O: quadrangular 2 headed muscle from 1) medial surface of lateral pterygoid plate and pyramidal process of palatine bone and 2) tuberosity of maxilla
I: Medial surface of rams of mandible, inferior to mandibular foramen; in essence, a mirror image of ipsilateral masseter two muscles flanking rams N: mandibular nerve O: acts synergistically with masseter to elevate mandible; contributes to protrusion; alternate unilateral activity produces smaller grinding movements |
|
|
What are the actions of the supra hyoid muscles?
|
depresses mandible against resistance when infra hyoid muscles fix or depress hyoid bone
|
|
|
What are the actions of the infrahyoid muscles?
|
fixes or depresses hyoid bone
|
|
|
Biting tongue what happens?
|
taste is from facial nerve; pain is from trigeminal nerve
|
