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

signals to the sympathetic nervous system. This causes the body to tense up and become more alert. The hypothalamus also releases CRF which activates the adrenal cortical system. The anterior pituitary gland begins the secrete adrenocorticotropic hormone directly into the bloodstream. When the ACTH reaches the adrenal cortex it stimulates the release of cortisol which increases the metabolism of proteins‚fats and carbohrdrates. Cortisol also increases blood sugar levels through gluconeogenesis. (1)

Neurotransmitters are released and travel through terminals in the brain until they reach certain receptors. Neurotransmitters and their functions are located and carried out in different sections of the brain. It uses neurotransmitters to make

“NEURAL CONTROL AND CO-ORDINATION” Co-ordination - It is the process through which two or more organs interact and complement the functions of each other. Neuron - It is the functional and structural unit of nervous system. Therefore‚ the nervous system is also known as NEURAL SYSTEM. Neurons with longer projections are said to be the longest cells in our body. There are about 100 billion neurons and most of them exist in the brain. Some neurons have flask-shaped and are called Purkinje cells
