Branches from the common carotid, entering and traveling through the carotid canal, then the cavernous sinus, eventually branching into anterior and middle cerebral arteries.

Originating from the brachiocephalic and subclavian arteries, these travel through cervical vertebrae and then the foramen magnum, merging to form the basilar artery, which further divides into posterior cerebral arteries.

A circulatory network at the base of the brain, connecting major arteries and providing alternate pathways for blood flow if one artery is blocked.

Includes the posterior cerebral, posterior communicating, internal carotid, anterior cerebral, and anterior communicating arteries.

Spaces between dura layers, collecting blood from brain veins and draining it into the internal jugular vein.

Groups of neuronal cell bodies (gray matter nuclei) deep within the brain, crucial for movement control and coordination.

A structure within the basal ganglia, involved in motor control.

A structure within the basal ganglia, composed of the putamen and globus pallidus, involved in motor control.

Part of the lentiform nucleus, a component of the basal ganglia, involved in motor control.

Part of the lentiform nucleus, a component of the basal ganglia, involved in motor control.

Region of the brain surrounding the third ventricle, connecting the cerebrum to the midbrain, containing the thalamus and hypothalamus.

Paired masses of gray and white matter, acting as a relay station for sensory impulses to the cerebral cortex, located on each side of the third ventricle.

Small gland below the thalamus, controlling homeostasis, emotions, sexual behavior, and circadian rhythms, functioning as a link between nervous and endocrine systems.

Endocrine gland that secretes melatonin, regulating sleep rhythms.

Endocrine gland that releases hormones controlling growth, blood pressure, and lactation.

Essential part of the brain controlling vital functions like breathing and heart rate, composed of midbrain, pons, and medulla oblongata.

Part of the brainstem, containing fibers and tracts, including the cerebral peduncles and superior/inferior colliculi (vision and hearing), and substantia nigra and red nuclei.

Part of the brainstem, acting as a relay center for communication between spinal cord and brain, with nuclei for cranial nerves V-VIII and roles in respiration.

Most inferior part of the brainstem; continuation of the spinal cord, controlling breathing, heart rate, and blood pressure; contains nuclei for cranial nerves IX-XII.

Brain structure responsible for coordination, balance, and learned movements, located behind the brain stem.

Three protective membranes (dura mater, arachnoid mater, pia mater) surrounding the brain and spinal cord.

Outermost, tough meningeal layer; contains dural venous sinuses.

Middle meningeal layer with delicate trabeculae, separating it from the pia mater; contains the subarachnoid space filled with CSF.

Innermost, delicate, highly vascular meningeal layer, supporting blood vessels in the brain.

Clear, colorless liquid circulating around the brain and spinal cord, providing cushion and support.

Network of interconnected cavities (ventricles) within the brain where CSF circulates.

Spaces between layers of dura mater that collect blood from brain veins and drain it into the internal jugular vein.

A main venous sinus located along the superior sagittal suture of the skull, draining cerebral blood.

A main venous sinus located along the inferior sagittal suture of the skull, draining cerebral blood.

A main venous sinus that collects blood from other venous sinuses and drains into the confluence of sinuses.

Pair of venous sinuses that run horizontally along the lateral aspects of the skull and drain into the sigmoid sinus

Pair of venous sinuses that drain into the internal jugular vein.

Within the vertebral canal, continuous with the medulla oblongata, extending from the foramen magnum to the lower border of L1 (variable).

Nervous tissue link for nerve impulses to and from the brain; major reflex center and conduction pathway.

Cylindrical, slightly flattened shape, about the size of a little finger, tapers to a cone (medullary cone) at L1/L2.

Loose bundle of spinal nerve roots arising from the lower spinal cord.

Attaches the lower part of the spinal cord and meninges to the coccyx; anchoring structure.

Widening of the spinal cord in the cervical region, supplying nerves to the upper limbs.

Widening of the spinal cord in the lumbosacral region, supplying nerves to the lower limbs.

Centre of grey matter surrounded by white matter, divided by anterior and posterior fissures.
