Lab #8 The nervous system 5/26/2011 Objective- To understand how the nervous and endocrine systems work together in the body Procedure- 1.Obtain sheep brain and all utensils to dissect. 2.Put on gloves 3.Draw brain outside 4.Cut open brain 5.Draw brain inside 6.Label both drawings 7.Clean and disinfect all tools and station after disposing of brain in specified container Results- See drawings Vocab Corpus callosum- a thick band of nerve fibers that divides the cerebrum into left and right hemispheres Thalamus- A large ovoid mass of gray matter situated in the posterior part of the forebrain that relays sensory impulses to the cerebral cortex Hypothalamus- The part of the brain that lies below the thalamus, forming the major portion of the ventral region of the diencephalon and functioning to regulate bodily temperature, certain metabolic processes, and other autonomic activities. Pineal- a small endocrine gland in the vertebrate brain . It produces the serotonin derivative melatonin , a hormone that affects the modulation of wake/sleep patterns and seasonal functions Limbic system- is a set of brain structures including the hippocampus , amygdala , anterior thalamic nuclei , septum , limbic cortex and fornix, which seemingly support a variety of functions including emotion , behavior , long term memory , and olfaction . Cerebellum- a region of the brain that plays an important role in motor control

Pons- serves as a communications and coordination center between the two hemispheres of the brain. Medualla oblongata- a portion of the hindbrain that controls autonomic functions such as breathing, digestion and heart rate Ventricles- The ventricles are filled with cerebrospinal fluid, which is formed by structures called choroid plexuses located in the walls and roofs of the ventricles. Cerebral spinal fluid - a clear, colorless bodily fluid , that occupies the subarachnoid space and the ventricular system around and inside the brain and spinal cord . In essence, the brain "floats" in it. Spinal cord- a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain
