What is the blood vessel laden component of the vascular tunic?
Choroid
The choroid is rich in blood vessels and provides nutrients to the eye.
What is the white of the eye called?
Sclera
The sclera provides structure and protection to the eyeball.
Which part of the eye contains the pigmented and sensory layers?
Retina
The retina is responsible for converting light into neural signals.
What is the clear expansion of the fibrous tunic?
Cornea
The cornea allows light to enter the eye and helps focus it.
What is the opening in the lens that permits light into the inner chambers of the eye?
Pupil
The pupil adjusts in size to control the amount of light entering the eye.
What is the thick, jelly-like substance in the posterior compartment of the eye?
Vitreous humor
The vitreous humor maintains the shape of the eyeball.
What is the clear, plasma-like substance that bathes the lens and cornea?
Aqueous humor
The aqueous humor provides nutrients and maintains intraocular pressure.
What is the biconcave structure that changes shape to bring objects into focus?
Lens
The lens adjusts its shape to focus light on the retina.
What are the groups of axons in the CNS called?
White matter
White matter consists of myelinated axons that transmit signals.
What are neuron cell bodies referred to as?
Gray matter
Gray matter contains the cell bodies and is involved in processing information.
What is the hollow space filled with fluid inside the CNS tissue?
Ventricle
Ventricles are interconnected cavities that contain cerebrospinal fluid.
What are furrows in the brain called?
Sulcus
Sulci separate the gyri and increase the surface area of the brain.
What are twisters in the brain referred to as?
Gyrus
Gyri are the raised folds of the brain’s surface.
Which EEG brain wave pattern occurs when we are mentally alert?
Beta waves
Beta waves indicate active thinking and concentration.
Which EEG brain wave pattern is common in children and abnormal in awake adults?
Theta waves
Theta waves are associated with light sleep and relaxation.
Which EEG brain wave pattern indicates a calm, relaxed state of wakefulness?
Alpha waves
Alpha waves are present when a person is awake but relaxed.
Which EEG brain wave pattern is seen during deep sleep?
Delta waves
Delta waves are associated with the deepest stages of sleep.
Which cranial nerve supplies four of the six extrinsic eye muscles?
Oculomotor
The oculomotor nerve controls most eye movements.
Which cranial nerve is the sensory nerve of vision?
Optic
The optic nerve transmits visual information from the retina to the brain.
Which cranial nerve supplies sensory fibers to the face and motor fibers to the chewing muscles?
Trigeminal
The trigeminal nerve is responsible for sensation in the face and motor functions for chewing.
Which cranial nerve controls the extrinsic eye muscle that abducts the eyeball?
Abducens
The abducens nerve is responsible for lateral eye movement.
Which cranial nerve innervates an extrinsic eye muscle that loops through a pulley-shaped ligament in the orbit?
Trochlear
The trochlear nerve controls the superior oblique muscle of the eye.
What taste sensation is caused by proteins, amino acids, and monosodium glutamate?
Umami
Umami is often described as a savory taste.
What taste sensation is caused by table sugar and other carbohydrates?
Sweet
Sweetness is one of the primary taste sensations.
