Summary
The 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. The central nervous system consists of the brain and spinal cord and serves as the collection point of nerve impulses. The peripheral nervous system includes all nerves not in the brain or spinal cord and connects all parts of the body to the central nervous system. The somatic nervous system controls functions that are under conscious voluntary control such as skeletal muscles and sensory neurons of the skin. The autonomic nervous system, mostly motor nerves, controls functions of involuntary smooth muscles, cardiac muscles, and glands. In peripheral nervous system, a chemical neurotransmitter carries the nerve impulses from neuron to

    The nervous system consists of the central nervous system (CNS), made up of the brain and the spinal cord, and the peripheral nervous system (PNS), the neurons that link the CNS to our skin, muscles, and glands. And we will see that our behavior is also influenced in large part by the endocrine system, the chemical regulator of the body that consists of glands that secrete hormones.…

    SPECIAL SENSES GENERAL PRESENTATION Overview of the Nervous System • Endocrine and nervous systems maintain internal coordination – Endocrine system: communicates by means of chemical messengers (hormones) secreted into to the blood – Nervous system: employs electrical and chemical means to send messages from cell to cell 12-2 Overview of the Nervous System • Nervous system carries out its task in three basic steps • Sense organs receive information about changes in the body and external environment, and transmit coded messages to the brain and spinal cord (CNS: central nervous system) • CNS processes this information, relates it to past experiences, and determines appropriate response • CNS issues commands to muscles and gland cells to carry out such a response 12-3 Overview of the Nervous System • Two major subdivisions of nervous system – Central nervous system (CNS) • Brain and spinal cord enclosed by cranium and vertebral column – Peripheral nervous system (PNS) • All the nervous system except the brain and spinal cord; composed of nerves and ganglia • Nerve—a bundle of nerve fibers (axons) wrapped in fibrous connective tissue • Ganglion—a knot-like swelling in a nerve where neuron cell bodies are concentrated 12-4 Overview of the Nervous System • Peripheral nervous system contains sensory and motor divisions each with somatic and visceral subdivisions – Sensory (afferent) division: carries signals from receptors to CNS • Somatic sensory division: carries signals from receptors in the skin, muscles, bones, and joints • Visceral sensory division: carries signals from the viscera (heart, lungs, stomach, and urinary bladder) 12-5 Overview of the Nervous System • Motor (efferent) division—carries signals from CNS to effectors (glands and muscles that carry out the body’s response) – Somatic motor division: carries signals to skeletal muscles • Output produces muscular contraction as well as somatic reflexes—involuntary muscle contractions –…

    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 fibers); some nerves contain only sensory nerve fibers (afferent fibers); and some nerves contain both sensory and motor nerve fibers (mixed). All spinal nerves are mixed. Cranial nerves…

    The nervous system’s function is to monitor stimuli occurring inside and outside the body, process and interpret this sensory input, and respond by activating effector organs. It consists of the Central Nervous System (brain and spinal cord), and the Peripheral Nervous System (neurons that carry messages to and from the CNS).…

    The nervous system consists of two parts, the central nervous system (CNS) and the peripheral nervous system (PNS) (National Institute of Health [NIH], 2013). Each part plays a role in our bodily functions. The CNS is made up of the brain and the spinal cord, the PNS is made up of the all the branch-like fibers that come off the spinal cord and reach all over the body- arms, legs, face, neck, etc. Without the nervous system there would be no way to get information from the brain to the rest of the body; all the messages that our brain sends out must be sent though the nervous system through neuron communication. "Neurons communicate with each other using axons and dendrites. When a neuron receives a message from another neuron, it sends an electrical signal down the length of its axon. At the end of the axon, the electrical signal is converted into a chemical signal, and the axon releases chemical messages called neurotransmitters" (NIH, ¶ 3). This process is how the brain tells the body to walk or blink or…

    Inside our brain, there is this system called the human nervous system. There are two types of nervous systems: the peripheral and central nervous systems. The peripheral nervous system includes the nerves connecting the central nervous system to the rest of the body. It has two subdivisions: somatic nervous system and autonomic nervous system. Somatic nervous system controls skeletal muscles and interacts with the external environment. An example is walking through a park. You are using your motor nerves, which relay messages from the central nervous system, to all the skeletal muscles of your body. The autonomic nervous system regulates the body’s internal environment, which consists of organs, glands, and blood vessels. An example is breathing.…

    The human Body is a very complex organism. It is composed of many different organs systems, which are vital for the body to function properly. They work with one another in order to carry out daily life activities and maintain the body’s proper functions. Among these organ systems lies one of the most important, the nervous system. The nervous system functions as the control center of the body, and it is in charge of the activities of the rest of the organs systems and the body’s components (Marieb, E.N. & Hoehn, K.). It helps the body communicate external environmental factors via electrical impulses that are transmitted through cells called neurons. These neurons can be up to a meter long and target a specific effector which it will help…

    In humans, the nervous system is divided into the central nervous system (CNS), which consist of the brain and spinal cord, and the peripheral nervous system (PNS), which contains all the nerves that run everywhere in the body. The brain and the spinal cord serve as the main processing center for the entire nervous system, and control all the workings of the human body. They work together to let messages flow back and forth between the brain and the body.…
