PPT-LECTURE NERVOUS TISSUE

NERVE TERMINATIONS The nerve fiber traveling in peripheral nerves terminate in peripheral structures to which or from which they convey nerve impulses Accordingly the nerve terminations are classified into two major groups. Biol 105. Lecture Packet 10. Chapter 8 . Outline. Central Nervous System vs Peripheral Nervous System. Peripheral Nervous System. Autonomic Nervous Systems. Somatic Nervous Systems. Autonomic Nervous System. NERVOUS SYSTEM. NERVOUS SYSTEMS RECEIVE SENSORY INPUT, INTEPRET IT, AND SENT OUT APPROPRIATE COMMANDS. NERVOUS SYSTEMS. MOST INTRICATELY ORGANIZED DATA PROCESSING SYSTEM ON EARTH. NEURON. FUNCTIONAL UNIT; SPECIALIZED NERVE CELL FOR CARRYING SIGNALS FROM ONE LOCATION IN THE BODY TO ANOTHER. A). Neurology. – study of nervous system. B) . neuron. s. – conducting cells of the nervous system, normally do not divide (non-mitotic). C) . neuroglia. – supporting cells of the nervous system, mitotic, numerous. A. Bacterial Infections of the Nervous System. 1. Bacterial Meningitis. A) Although bacteria can infect the brain, spinal cord, and peripheral nerves, they more commonly infect the meninges and cerebrospinal fluids resulting in meningitis. Functions of the Nervous System. Sensory input. Information gathered by sensory receptors about internal and external changes . Integration. Interpretation of sensory input. Motor output. Activation of effector organs (muscles and glands) produces a response. 1. nervous system overview. Nervous system.

Tiniest bones are in the inner ear . Longest bone in the body is your thigh bone. Functions of the skeletal system. Nervous System Lecture Objectives. Describe the anatomical and functional organization of the nervous system.. Describe the histologic features of neurons, their processes, and synapses.. Describe the histologic features and functions of glial cells.. Central nervous system comprises the brain and the spinal cord with nervous tissue making up the system. This system is the most intricate system in human body.. The nervous tissue consists of rich network of billions of nerve cells in both the CNS and PNS . AUTONOMIC NERVOUS SYSTEM. Two major subdivision. Parasympathetic . cranio. -sacral outflow. Sympathetic . . thoraco. -lumbar out flow. Responsible for the visceral control. Sometimes referred to as vegetative control. :. by.
