Tectum The tectum (Latin: roof) is a region of the brain, specifically the dorsal part of the mesencephalon (midbrain). This is contrasted with the tegmentum, which refers to the region ventral to the ventricular system. The tectum is responsible for auditory and visual reflexes.

Metencephalon The metencephalon is the embryonic part of the hindbrain that differentiates into the pons and the cerebellum. It contains a portion of the fourth ventricle and the trigeminal nerve (CN V), abducens nerve (CN VI), facial nerve (CN VII), and a portion of the vestibulocochlear nerve (CN VIII).

- The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus (part of the limbic system). The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla. Often the midbrain, pons, and medulla are referred to together as the brainstem. The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called lobes: the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.

The Brain Stem Caudally the midbrain adjoins the metencephalon (afterbrain) (pons and cerebellum) while rostrally it adjoins the diencephalon (thalamus, hypothalamus, etc.). The midbrain is located below the cerebral cortex, and above the hindbrain placing it near the center of the brain.

What Are the Functions of the Midbrain? The midbrain region is part of the central nervous system. It is located near the center of the brain, under the cerebral cortex and on top of the hindbrain region. This region joins the spinal cord and the brain together and is commonly referred to as part of the brainstem primarily due to its location.

Generally speaking, the right cerebral hemisphere controls the left side of the body and the left cerebral hemisphere controls the right side of the body.he midbrain is the short portion of the brain stem between the pons and the cerebral hemispheres. The top of the midbrain is called the tectum (or tectal area). The third and fourth cranial nerves originate in the midbrain. Pons.

Forebrain At the five-vesicle stage, the forebrain separates into the diencephalon (thalamus, hypothalamus, subthalamus, epithalamus, and pretectum) and the telencephalon which develops into the cerebrum. The cerebrum consists of the cerebral cortex, underlying white matter, and the basal ganglia.Redirected from Prosencephalon). In the anatomy of the brain of vertebrates, the forebrain or prosencephalon is the rostral-most (forward-most) portion of the brain.

Brainstem: Its Function and Location The brainstem is composed of the midbrain and portions of the hindbrain, specifically the pons and medulla. A major function of the midbrain is to connect the three major brain divisions: forebrain, midbrain, and hindbrain. Major structures of the midbrain include the tectum and cerebral peduncle. The tectum is composed of rounded bulges of brain matter that are involved in visual and auditory reflexes.

The innermost layer of the Earth is called what? What is the innermost layer of the heart wall called? The endocardium is the innermost layer of the heart wall. What is the innermost meningeal layer of the brain called? The pia mater is the delicate innermost layer of the meninges-the  membranes surrounding the brain and spinal cord. It is delicate and  vascular, and follows every contour o…f the brain.

Brainstem: Its Function and Location Brainstem: The brainstem is the region of the brain that connects the cerebrum with the spinal cord. It consists of the midbrain, medulla oblongata, and the pons. Motor and sensory neurons travel through the brainstem allowing for the relay of signals between the brain and the spinal cord. The brainstem coordinates motor control signals sent from the brain to the body.

Midbrain The tectum (from Latin for “roof”) makes up the rear portion of the midbrain and is formed by two paired rounded swellings, the superior and inferior colliculi. The superior colliculus receives input from the retina and the visual cortex and participates in a variety of visual reflexes, particularly the tracking of objects in the visual field.

- The Midbrain (mesencephalon) The mesencephalon is the most superior part of the brainstem. It is divided into an anterior and a posterior section by the Aqueduct of Sylvius which connects the third and fourth ventricles. Motor tracts, including the fibers of the pyramidal system, pass downward on the midbrain's anterior surface.
