Page 429 #’s 1-7 1. List the three major parts of the brain and describe their locations. A. cerebrum- constitutes about 83% of its volume and consists of a pair of half-globes called the cerebral hemispheres. B. cerebellum- lies inferior to the cerebrum and occupies the posterior cranial fossa. C. brainstem- that which remains of the brain if the cerebrum and cerebellum are removed. 2. Gyrus- a wrinkle or fold in the cortex of the cerebrum or cerebellum. Sulcus- a groove in the surface of

The Brain has five major structures . These structures include the mesencephalon‚ metencephalon‚ myelencephalon (or medulla)‚ telencephalon‚ and diecephalon. All of these brain structures contribute different functions within the human body. The brain’s first structure is the myelencephalon‚ which is also called the medulla. The myelencephalon is known as the most posterior part of the brain. The structure of the myelencephalon is made up of bundles of axons called tracts. These tracts carry

1. Biological psychologists are gaining a better understanding of our experiences of sights and sounds‚ meanings and memories‚ pain and passion. Franz Gall invented phrenology‚ a popular theory that claimed that bumps on the skull reveal our mental abilities and our character traits. Although wrong‚ this information revealed that various brain regions have specific functions. 2. A neuron consists of a cell body and branching fibers:The dendrite fibers receive information from sensory

Question 1. a. Develop an outline of the components of the human nervous system‚ inclusive of the CNS (central nervous system) the somatic system‚ and both divisions of the autonomic nervous system (ANS). Include in your outline the major distinctions among these systems. Human Nervous System – Overview The human nervous system is composed of all nerve tissues in the body. The functions of nerve tissue are to receive stimuli‚ transmit stimuli to nervous centers‚ and to initiate response

1. Describe the general structure and function of the nervous system. The Nervous System is a "network" which delivers information and monitors the processes taking place in our bodies at all times. The nervous system in all its aspects allows us to function as a single controlled and coordinated unit. The basic nerve cell nerve cell is a neuron; a chain of neurons is actually a "communication cable "inside our bodies. Neuron structure is basically the cell nucleus‚ the dendrites which receive information
