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.

Cerebrum The cerebrum is a large part of the brain containing the cerebral cortex (of the two cerebral hemispheres), as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In humans, the cerebrum is the superior-most region of the central nervous system. The telencephalon is the embryonic structure from which the cerebrum develops prenatally.

Chapter 8B - Cerebellar Systems The cerebellum is connected to the brain stem by three peduncles. The middle peduncle is, by far, the largest of the peduncles, connecting the pons to the cerebellum. The inferior peduncle connects the medulla to the cerebellum, while the superior peduncle connects the cerebellum to the midbrain.

- Varieties with white, pink, and many shades of blue are available, as are dwarf versions that form clumps that are about 8-12 in (20.3-25.4 cm) in height. Mexican petunia is very showy when in full bloom due to the clouds of admiring butterflies that swarm about the plants. Here's a palette of Mexican petunia varieties: the purple and pink at the top are standard varieties with long stems. The blue and white flowers at the bottom are dwarf varieties that stay below 12 in (30.5 cm) in height.

A Tour of the Brain The more recently developed areas — the cerebellum and the cerebrum — surround the brain stem. The cerebellum is a cauliflower-shaped structure, located just above the brain stem, beneath the occipital lobes at the base of the skull. The cerebellum regulates muscle tone, coordinates movement and helps maintain posture and balance. The cerebellum has two halves, similar to the cerebrum.

- 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.

CHAPTER 17. THE CEREBRAL VENTRICLES Cerebral Aqueduct (of Sylvius) The cerebral aqueduct or iter is located in the midbrain and connects the third and fourth ventricles (Pls. 12, 13, MRIs 12, 13, 14). The fourth ventricle is a single cavity whose rhomboid shaped floor is in the roof of the pons and rostral medulla.

A Tour of the Brain The cerebellum is a cauliflower-shaped structure, located just above the brain stem, beneath the occipital lobes at the base of the skull. The cerebellum regulates muscle tone, coordinates movement and helps maintain posture and balance.he midbrain — the uppermost part — has fibers that connect the brain stem to the cerebrum and cerebellum; this area is very important in the control of skeletal movements. The pons, which lies between the midbrain and medulla oblongata, relays sensory information between the cerebrum and cerebellum.
