Handout Lab 5 - Cranial Nerves: Assessment of Functions INTRODUCTION The central nervous system (CNS) consists of the brain and the spinal cord. The CNS receives sensory information from other parts of the body or the body’s external environment and transmits motor information to other parts of the body by way of the peripheral nervous system (PNS). The PNS of the human includes 31 pairs of spinal nerves and 12 pairs of cranial nerves. Some nerves contain only motor nerve fibers (efferent

is activated by the rise in blood temperature and is responsible for for controlling the mechanisms that will decrease the blood temperature. Efferent nerve impulses are sent from the hypothalamus to multiple different corrective mechanisms to try to decrease the blood temperature and maintain it at approximately 37℃. The efferent nerve impulses causes the smooth muscles to relax and as a result‚ opens up blood capillaries near the surface of the skin. This is known as vasodilation as the blood

Cnidarians have radially symmetrical bodies organized around a gastrovascular cavity. In hydras‚ neurons controlling the contraction and expansion of the gastrovascular cavity are arranged in diffuse nerve nets. The nervous systems of more complex animals contain nerve nets‚ as well as nerves‚ which are bundles of fiber like extensions of neurons. With cephalization come more nervous systems that are complex. Neurons are clustered
