Neuroanatomy: Telencephalon and Related Structures

These flashcards cover the anatomical structures and functions related to the telencephalon and other important parts of the brain.

Telencephalon

The most developed part of the brain, comprising the cerebrum and responsible for higher brain functions.

Cerebrum

The largest part of the brain, divided into lobes, responsible for voluntary activities, thought, and perception.

Longitudinal fissure

The deep groove that divides the brain into left and right hemispheres.

Transverse fissure

The separation between the cerebellum and the cerebrum.

Central sulcus

The prominent groove that separates the frontal lobe from the parietal lobe.

Lateral sulcus

Also known as the Sylvian fissure, it separates the temporal lobe from the frontal and parietal lobes.

Pre-central gyrus

The area of the frontal lobe that is involved in the control of voluntary motor functions.

Post-central gyrus

The area of the parietal lobe associated with the processing of sensory information.

Optic nerves and optic chiasma

The nerves that convey visual information from the retina to the brain, where they partially cross.

Olfactory bulbs

Structures that receive neural input about odors from the olfactory receptors.

Lateral ventricles

Cavities within the brain that produce and contain cerebrospinal fluid.

Corpus callosum

The bundle of nerve fibers that connects the left and right cerebral hemispheres.

Fornix

A C-shaped bundle of fibers in the brain that carries signals from the hippocampus to the hypothalamus.

Thalamus

The brain's relay station, processing and transmitting sensory information.

Third ventricle

A narrow cavity located in the middle of the brain, part of the ventricular system.

Choroid plexus

A network of cells that produce cerebrospinal fluid in the ventricles of the brain.

Pineal gland

A small endocrine gland that produces melatonin, regulating sleep-wake cycles.

Hypothalamus

The region of the brain that controls various autonomic functions and regulates hormonal activity.

Pituitary gland and infundibulum

The master endocrine gland that controls other glands and is connected to the hypothalamus by the infundibulum.

Mammillary body

A pair of small round bodies located on the underside of the brain, involved in memory processing.

Midbrain

The part of the brainstem associated with vision, hearing, motor control, sleep/wake cycles, and temperature regulation.

Corpora quadrigemina

The four protrusions on the dorsal side of the midbrain involved in visual and auditory reflexes.

Superior and Inferior colliculi

The upper (superior) and lower (inferior) pairs of bumps on the midbrain important for visual and auditory processing.

Cerebral aqueduct/midbrain aqueduct

The channel connecting the third and fourth ventricles, allowing the flow of cerebrospinal fluid.

Pons

The part of the brainstem that connects the cerebellum to the rest of the brain and regulates breathing.

4th ventricle

The cavity located between the brainstem and the cerebellum, containing cerebrospinal fluid.

Central canal

A small channel in the spinal cord that is filled with cerebrospinal fluid.

Cerebellum

The part of the brain that coordinates voluntary movements and maintains posture and balance.

Arbor vitae

The white matter structure within the cerebellum that resembles a tree.

Medulla oblongata

The lower part of the brainstem that controls vital functions such as heart rate and respiration.
