The Human Brain: Brain Stem, Cerebellum, and Nerves

Name the part and function(s)

The Midbrain (Involved in vision, hearing, and motor control; inferior to the diencephalon)

Name the part and function(s)

Cerebral Aqueduct (A passageway that runs through the mid brain. Allows CSF to flow from the third ventricle to the fourth)

Name the part and function(s)

The Midbrain (Involved in vision, hearing, and motor control; inferior to the diencephalon)

Name the part and function(s)

Cerebral Aqueduct (A passageway that runs through the mid brain. Allows CSF to flow from the third ventricle to the fourth)

Name the part and function(s)

Tectum (A region of the brain involved in auditory and visual reflexes )

Name the part and function(s)

Superior Colliculus (involved in visual reflexes, like the coordination of eye and head movement as well as hand movement)

Name the part and function(s)

Inferior Colliculus (Involved in auditory reflexes like the startle reflex where one might turn their head and body towards a loud noise)

Name the part and function(s)

Oculomotor Nerves (A cranial nerve responsible for controlling a variety of muscles involved in eye movement as well as dilation and constriction of the pupil)

Name the part and function(s)

Pineal Gland (Produces Melatonin; a hormone involved in the sleep cycles)

Name the part and function(s)

Pons (Basically the bridge that connects the diencephalon and cerebellum to the cerebellum and medulla oblongata; Pons contain nuclei involved in functions like chewing, breathing, and more)

Name the part and function(s)

Medulla Oblongata (contains motor tracts ventrally and sensory tracts dorsally, and nuclei; involved in breathing, vomiting, and sneezing)

Name the part and function(s)

Folia (Small folds in the Cerebellum)

Name the part

Arbor Vitae

Name the part and function(s)

Fourth Ventricle (It receives CSF from the 3rd ventricle (Via the cerebral aqueduct allows it to move inferiorly into the central canal of the spinal cord)

Name the part and function(s)

Transverse Fissure (Separates the cerebellum and the occipital lobe of the cerebrum)

Name the part

Vermis

Name the part and function(s)

Olfactory Bulb (It receives input from olfactory neurons coming from the nasal cavity)

Name the part and function(s)

Olfactory Tract (Carries olfactory information to the cerebrum where it can be sorted, processed, and interpreted)

Name the part and function(s)

Optic Nerve (Carries axons from the retina of the eye; cranial nerve II)

Name the part and function(s)

Optic Chiasm (The site at which some axons in each optic nerve cross over to the other side

Name the part and function(s)

Optic Tract (Each tract carries axons from both optic nerves onward to the thalamus)

Name the part

Oculomotor Nerve

Name the part and function(s)

Trigeminal Nerve (Trigeminal nerve is cranial nerve V it carries sensory info from the fact and motor commands to chewing muscles)
