Human Anatomy: Exam V
What are the three paired structures that compose the Diencephalon?
Thalamus, Hypothalamus, and Epithalamus.
What is the primary function of the Cerebellum?
It smooths and coordinates movement, helping to maintain posture and equilibrium.
What is the role of the Thalamus in the brain?
It serves as the gateway to the Cerebrum.
What is the function of the Hypothalamus?
It acts as the visceral control center.
What does the Pineal gland secrete?
Melatonin.
What is the largest portion of the brain called?
The Cerebrum, which is made up of various lobes and fissures.
What are the three paired structures of the brain?
Thalamus, Hypothalamus, and Epithalamus.
What are the major lobes of the brain?
Parietal lobe, Frontal lobe, Occipital lobe, and Temporal lobe.
Which cranial nerve is responsible for olfaction?
Olfactory Nerve (CN I).
What is the function of the Optic Nerve (CN II)?
Sensory: Vision.
Which cranial nerve controls extrinsic eye muscles?
Oculomotor Nerve (CN III).
What is the function of the Trochlear Nerve (CN IV)?
Motor: Controls the superior oblique muscle of the eye.
What is the primary function of the Trigeminal Nerve (CN V)?
Motor: Mastication; Sensory: Face and oral cavity.
What are the three divisions of the Trigeminal Nerve (CN V)?
Ophthalmic division (V1), Maxillary division (V2), and Mandibular division (V3).
What is the function of the Abducens Nerve (CN VI)?
Motor: Controls the lateral rectus muscle, abducting the eye.
What is the role of the Facial Nerve (CN VII)?
Motor: Facial muscles; Sensory: Anterior tongue (taste) and glands.
Which cranial nerve is responsible for hearing and balance?
Vestibulocochlear Nerve (CN VIII).
What is the function of the Glossopharyngeal Nerve (CN IX)?
Motor: Pharynx and parotid gland; Sensory: Posterior tongue (taste) and barometric
(Carotid sinus).
What does the Vagus Nerve (CN X) control?
