Mixed nerve for sensations and controlling several internal organs.

Located below the midbrain, above the medulla oblongata.

Located at the base of the brain, in the middle cranial fossa, about 10 mm above the pituitary gland

The "master gland" that regulates many body functions, including hormone levels and involuntary nervous system.

Located below the pons and above the spinal cord.

A portion of the brainstem that sits above the pons and below the diencephalon.

Located at the base of the brain, in the sella turcica

Located in the middle of the brain, in the epithalamus, where the two brain hemispheres meet.

Located in the center of the brain, above the brainstem, and between the cerebral hemispheres.

Part of the diencephalon, a brain area that includes the hypothalamus and epithalamus.

Below the thalamus, above the pituitary gland, and directly above the brainstem.

Posterior surface of midbrain, just below the thalamus.

A branch of the brachial plexus that supplies muscles in the anterior forearm and intrinsic muscles of the hand, as well as skin on the medial side of the hand and forearm.

A branch of the brachial plexus that supplies the posterior muscles of the arm and forearm, including extensors.

A branch of the brachial plexus responsible for the deltoid and teres minor muscles, supplying sensation to the shoulder region.

Innervates rhomboid and levator scapulae muscles.

Supplies the serratus anterior muscle.

Innervates subscapularis and teres major muscles.

Supplies the latissimus dorsi muscle.

Innervates supraspinatus and infraspinatus muscles.

Innervate the pectoralis major and minor muscles.

Innervates the anterior compartment of the thigh, including quadriceps, sartorius, pectineus, and iliacus.

Innervates the eye muscle that moves the eye through a pulley-like ligament.

A nerve with three branches that provides feeling to the face and controls chewing muscles.

Controls the eye muscle that moves the eye sideways.

Controls facial muscles and other related senses.

A nerve that helps with hearing and balance.

A nerve connected to the tongue and pharynx (throat).

A nerve that travels outside the head to the chest and abdomen.

Motor nerve, once called the spinal accessory nerve, associated with neck and shoulder movement.

Controls muscles in the tongue.

Located below the midbrain and above the medulla oblongata.

Located below the pons and above the spinal cord.

A portion of the brainstem above the pons and below the diencephalon.

Located in the center of the brain, above the brainstem, and between the cerebral hemispheres.

Located below the thalamus, above the pituitary gland, and directly above the brainstem.

On the posterior surface of the midbrain, just below the thalamus.

A major relay center for sensory information and involved in regulating consciousness and alertness.

Controls vital functions like hormone release, body temperature, hunger, and thirst.

Primarily involved in visual and auditory reflexes.

A fissure on the superior surface of the cerebral hemisphere, separating the frontal lobe from the parietal lobe and the primary motor cortex from the primary sensory cortex

A fissure on the lateral surface of the cerebral hemisphere, separating the frontal and parietal lobes from the temporal lobe. It's so deep it's sometimes called a fissure, not a sulcus.

A fissure on the posterior surface of the cerebral hemisphere, separating the parietal lobe from the occipital lobe.

Part of the frontal lobe, directly in front of the central sulcus. It's the primary motor cortex.

Part of the parietal lobe, directly behind the central sulcus. It's the primary somatosensory cortex.

A deep fissure separating the left and right cerebral hemispheres.

Separates the cerebellum from the cerebral hemispheres.

The anterior part of the cerebrum.

The posterior, superior part of the cerebrum.

The lateral part of the cerebrum.

The posterior, inferior part of the cerebrum.

A deep lobe located within the cerebrum, hidden beneath the frontal, parietal, and temporal lobes.

Located within the brain's ventricles, lining the lateral ventricle's floor and the third and fourth ventricle's roof.

Situated in the anterior part of the fornix columns, crossing the brain's midline to connect hemispheres.

In the brain's midline, between the cerebral hemispheres, connecting to the corpus callosum and fornix.

Located on the medial side of the cerebral hemispheres, a C-shaped bundle of white matter.

Located on the undersurface of the brain, a pair of small round bodies in the diencephalon.

Located just above the thalamus.

Branch of brachial plexus; supplies muscles in the anterior forearm, intrinsic hand muscles, and skin of medial hand/forearm.

Branch of brachial plexus; supplies posterior arm/forearm muscles, including extensors.
