That's how eye roll
The white portion of the eye.
Sclera
Collects sound waves from the environment.
Pinna (auricle)
Olfactory receptor cells are ________ neurons.
Bipolar
The main component of the inner neural layer of the eye.
Retina
Anatomical name for the 'eardrum' and its purpose.
Tympanic membrane - amplifies sound & transmits sound waves to the middle ear.
Elevations on the tongue that contain the taste buds.
Papillae
The 'blindspot of the eye.' (*bonus: what causes this?)
optic disc; exit pathway of optic nerve from the eye
Ossicles found in the middle ear (in order from tympanic membrane to oval window).
Malleus - incus - stapes
Innervates the anterior 2/3 of the tongue.
Facial nerve (CN VII)
The anterior cavity contains ________ humor while the posterior cavity contains _________ humor.
aqueous (watery liquid, transparent)
vitreous (thicker, gel-like fluid that maintains shape of the eye)
The components of the external middle, and internal ear.
External ear - auricle (pinna), external acoustic meatus/canal
*Tympanic membrane separates external and middle ear.
Middle ear - ossicles (malleus, incus, stapes)
Internal ear - cochlea (hearing component), vestibule (static equilibrium), and semicircular canals (dynamic equilibrium)
The brain lobe that contains the primary gustatory area (conscious perception of taste).
Insula
When looking at a nearby object, the ciliary muscle _______ and the lens becomes ________.
When looking at a distant object, the ciliary muscle ______ and the lens _________.
contracts; rounder
relaxes, flattens
The three systems that control posture/balance.
The # of these systems needed for balance.
1. Visual system
2. Vestibular system
3. Somatosensory system
Inputs from TWO are required to maintain balance.
The olfactory pathway from external nares to CN I.
External nares - axons from neurons in olfactory bulb (extend through olfactory foramina in cribriform plate) - olfactory tract - primary olfactory area (temporal lobe)
