3. mandibular br. (out mental foramen as mental n.)

DEEP - sensor, which is why it surfaces thr. foramen

also does motor to muscles of mastification (

Front 33

4 signs of HORNER'S SYNDROME

Back 33

1. Ptosis - (from Greek Ptosis or πτῶσις, to "fall") (drooping) of upper or lower eyelid.

2. Enopthalmos - protruding eyeball anteriorly out of orbit (eye socket). Greek word ophthalmos means "eye" and ex means "out".

3. Protruding 3d Eyelid

4. Miosis (or myosis): is constriction of the pupil

All stem from interruption of sympathetic
innervation to the eye.

note: important to distinguish ptosis caused by Horner's syndrome from ptosis caused by lesion to oculomotor nerve. According to wiki, former b/c loss of sympathetic to eye and later ptosis occurs with dilated pupil (due to a loss of innervation to the sphincter pupillae). But I think it's the other way around!

"Horny PAMELa"

Front 34

Opposite of miosis

Back 34

Mydriasis, which is excessive dilation of the pupil

Front 35

pupillary light reflex

Back 35

controls diameter of pupil, in response to intensity (luminance) of light that falls on retina of eye

Afferent fibers via optic nerve, while oculomotor nerve is responsible for efferent limb of pupillary reflex - driving muscles that constrict pupil.

Loss of reflex on same side (ipsilateral) as lesion.

Front 36

Ptosis

Back 36

“toe-sis”, drooping of eyelid

One sign of Horners!

Front 37

Skip until know everything else!

CHOROID

CILIARY BODY

Back 37

Along w/ iris (most anterior) these are parts of vascular tunic (mid tunic) of eye!

- vascular supply to optical retina. Contains pigment (iris also has), and TAPETUM LUCIDUM

- suspends lens, contains smooth muscle for accommodation; has PROCESSES
covered by secretory epithelium.

Front 38

Miosis

Back 38

(or myosis, from Ancient Greek μύειν, mūein, "to close the eyes") is CONSTRICTION of the pupil
