The most obvious features of a lateral view of the brain are the lobes of the cerebrum and the cerebellum. The most anterior lobe is the frontal lobe, which is responsible for intellect and abstract reasoning, among other things. The division between the frontal lobe and the parietal lobe is the central sulcus. Just anterior to the central sulcus is the precentral gyrus, an area that sends motor impulses to muscles of the body. Just posterior to the central sulcus is the postcentral gyrus. The postcentral gyrus receives sensory information from the body. On the lateral aspect of the brain is the lateral fissure and inferior to this is the temporal lobe of the brain. Hearing, taste, smell, and the formation of memories all have centers here. The most posterior part of the cerebrum is the occipital lobe, which has visual interpretation areas. Label the regions seen in a lateral view of the brain and the spinal cord. Color the precentral and postcentral gyri and then color the lobes of the brain. Shade in the cerebellum as well.
Answer Key: a. Temporal lobe, b. Lateral fissure, c. Frontal lobe, d. Precentral gyrus, e. Central sulcus, f. Postcentral gyrus, g. Parietal lobe, h. Occipital lobe, i. Cerebellum

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
