- Several important nuclei are located in the midbrain, including the red nuclei, the substantia nigra, and the nuclei of cranial nerves III and IV. The red nuclei connect the midbrain to the cerebellum and to the inner ear. It is also an important part of the extra pyramidal tract.he corpora quadrigemina, which is located on the posterior surface of the midbrain, is composed of two superior colliculi and two inferior colliculi. The superior colliculi are part of the visual system, relaying input from the optic tract to the lateral geniculate bodies of the thalamus.

- The diencephalon or interbrain is one of the major regions of the brain in vertebrates. It consists of several structures between the brainstem and the cerebrum, including the thalamus, hypothalamus, epithalamus, pituitary gland, and pineal gland.Embryologically, the diencephalon begins as the region of the embryonic vertebrate neural tube that gives rise to posterior forebrain structures.he optic nerve (CNII) attaches to the diencephalon. The optic nerve is a sensory (afferent) nerve responsible for vision; it runs from the eye through the optic canal in the skull and attaches to the diencephalon. The retina itself is derived from the optic cup, a part of the embryonic diencephalon.

What is the brain made of and? 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.he Cerebellum: The cerebellum, or little brain, is similar to the cerebrum in that it has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance.

Hindbrain Pons is situated below the midbrain and above the medulla oblongata anterior to the cerebellum. It is mainly composed of those nerve fibers that connect the two halves of cerebellum. In addition, it also contains the ascending and descending fibers connecting the forebrain, midbrain and the spinal cord.edulla oblongata: It is the inferior-most component of brain that is continuous below with the spinal cord. Structurally, it is conical in shape and contains a median fissure on the anterior surface, on either side of which is a swelling called the pyramid.

Basic Parts of the Brain and Their Responsibilities The brainstem consists of the midbrain and the hindbrain. Just as the name suggests, the brainstem resembles the stem of a branch. The midbrain is the upper part of the branch that is connected to the forebrain. This region of the brain sends and receives information. Data from our senses, such as the eyes and ears, are sent to this area and then directed to the forebrain.

- Midbrain. The midbrain, also called the mesencephalon, is a small region of the brain that serves as a relay center for visual, auditory, and motor system information. It regulates autonomic functions, those that the body carries out without conscious thought, such as digestion, heart rate, and breathing rate.

Forebrain - Anatomy & Physiology Other important structures found in the forebrain include the thalamus, the hypothalamus and the limbic system. The cerebrum is divided into two cerebral hemispheres connected by a mass of white matter known as the corpus callosum. Each hemisphere is split into four lobes; the frontal, parietal, occipital and temporal lobes.

The Central Nervous System It consists of three parts: midbrain, pons, and medulla oblongata. The midbrain is the most superior portion of the brain stem. The pons is the bulging middle portion of the brain stem. This region primarily consists of nerve fibers that form conduction tracts between the higher brain centers and spinal cord.

The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. It works to correlate several important processes, including consciousness, sleep, and sensory interpretation.

Neurons, Hormones, and the Brain The midbrain is the part of the brain that lies between the hindbrain and the forebrain. The midbrain helps us to locate events in space. It also contains a system of neurons that releases the neurotransmitter dopamine.he Hindbrain. The hindbrain is composed of the medulla, the pons, and the cerebellum. The medulla lies next to the spinal cord and controls functions outside conscious control, such as breathing and blood flow.

Midbrain From Wikipedia, the free encyclopedia. The midbrain or mesencephalon (from the Greek mesos, middle, and enkephalos, brain) is a portion of the central nervous system associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation.he mesencephalon is considered part of the brainstem. Its substantia nigra is closely associated with motor system pathways of the basal ganglia. The human mesencephalon is archipallian in origin, meaning that its general architecture is shared with the most ancient of vertebrates.

- The inferior colliculi are part of the auditory pathway and send information to the medial geniculate bodies of the thalamus. Several important nuclei are located in the midbrain, including the red nuclei, the substantia nigra, and the nuclei of cranial nerves III and IV.he pons, which is also part of the brain stem, is inferior to the midbrain and superior to the medulla. Its posterior border is separated from the cerebellum by the aqueduct of Sylvius, and more inferiorly, by the fourth ventricle.

Brain areas and their functions The brain is divided into areas which are each responsible for different areas of functioning. The brain can be divided into three basic units: the forebrain, the midbrain and the hindbrain.These areas are: Occipital lobe, Temporal lobe, Parietal lobe, Frontal lobe. Cerebral cortex, Cerebellum, Hypothalamus,Thalamus,Pituitary gland, Pineal gland, Amygdala, Hippocampas and the Mid-brain.The image below indicates where the areas are. Occipital lobe: This is found in the back of the brain.The area is involved with the brain's ability to recognise objects. It is responsible for our vision.he image below indicates where the areas are. Occipital lobe: This is found in the back of the brain.

- SHARK LIVER OIL Overview Information. Shark liver oil is used to make medicine. It is taken from the livers of three species of shark: the deep sea shark (Centrophorus squamosus), the dogfish (Sqaulus acanthias), and the basking shark (Cetorhinus maximus). The liver makes up about 25% of the total shark body weight of these sharks. Shark liver oil is used along with usual cancer drugs to treat leukemia and other cancers; to prevent radiation illness from cancer X-ray therapy; to prevent the common cold, flu, and swine flu; and to boost the body’s immune system.

- Sleep and waking patterns are controlled in the forebrain. The forebrain controls many functions, including smelling. The largest part of the brain, the forebrain processes cognitive, auditory, visual and sensory information. Located in the forebrain, the hippocampus and amygdala are parts of the limbic system.he two main sections of the forebrain, however, are the telencephalon and the diencephalon. The telecephalon includes the cerebral cortex, the subcortical structures, and the corpus callosum, while the diencephalon includes the thalamus and the hypothalamus.
