Some of its larger branches run through the pelvic area. The two systems work together to collect information from inside the body and from the environment outside it.

The glial cells surround the neurons to hold them in place, supply them with oxygen and nutrients, isolate the neurons from one another and remove dead neurons. It runs down the arm and enters the forearm. Sensory. - Received 1 March 1978) [Plates 1-6] CONTENTS PAGE 1. One of the most complex organ system to ever evolve, the human nervous system consists of two parts, namely: Central Nervous System (consists of the brain and spinal cord) Peripheral Nervous System … The central nervous system (CNS) consists of the brain and the spinal cord, while the peripheral nervous system (PNS) consists of sensory neurons, ganglia (clusters of neurons) and nerves. It is around 45 cm long in men and 43 cm long in women. THE PEDUNCLE LOBES … The four main nerve plexuses in the human body are cervical plexus, brachial plexus, lumbar plexus and sacral plexus. Before you begin, you can take a quick peek at the already labeled diagram given above and see if you get the labels right! These signals are then passed on to the central nervous system (CNS) for further processing by afferent neurons (and nerves). © 2005-2020 Healthline Media a Red Ventures Company. It is located in the pelvic region and it supplies the external genitalia of both men and women. Respiratory Organs 6. Reproductive System 11.

I hope it helped you understand the nervous system function and parts and also gave you that ‘textbook feel’ while reading. Nerves are found only in the peripheral nervous system. She used to say, “The human body systems are the most accurately engineered machines that possess an intellect of their own. The PNS is composed of all the afferent and efferent neurons that extend from the CNS. The cerebrum is associated with information storage and processing; the cerebellum is responsible for balance, posture and coordination of movements; and the brain stem plays a vital role in controlling breathing and heart rate along with some other important body processes. Glia or glial cells, as they are called, are non-neural cells that play a vital role in maintaining homeostasis and protecting the brain’s neurons. Radial NerveIt is also a part of the brachial plexus. Well, we're looking for good writers who want to spread the word.

Chemicals and Drugs 8. These parts handle pieces of the brain’s overall workload, including storing and retrieving memory and making body movements smooth. The PNS can also be subdivided into smaller components: the somatic and autonomic systems. Functionally, the peripheral nervous system can be divided into two parts; the somatic nervous system and the autonomic nervous system, the somatic nervous system is responsible for bodily activities that are under conscious control.

Superficial Peroneal NerveIt supplies the peroneus longus, a muscle in the lateral compartment of the leg and the peroneus brevis, a smaller muscle lying under the peroneus longus. Coelom 4. In human beings, rather all vertebrates, the area where nerves branch and rejoin, is known as a plexus. Nervous system (anterior view) The nervous system is a network of neurons whose main feature is to generate, modulate and transmit information between all the different parts of the human body.This property enables many important functions of the nervous system, such as regulation of vital body functions (heartbeat, breathing, digestion), sensation and body movements. Let’s take a closer look at the central nervous system parts and functions. The nervous system is divided into two key parts: Cervical PlexusThe anterior branches of the upper four cervical nerves form a plexus in the neck region, and it is known as the cervical plexus.

The nervous system is a network of special cells, neurons and ganglia, that work together to carry out the transmission and reception of signals between different parts of our body. INTRODUCTION 275 2. The food is taken to the stomach region and then taken to what is known as the caecum. For me, diagrams and illustrations that textbooks carried, were always of great help in understanding the topic. Instead, the cell bodies (pericarya) of nerve cells are concentrated in nerve knots (ganglia) in important parts of the body. The systems process the collected information and then dispatch instructions to the rest of the body, facilitating an appropriate response. Hypersplenism. Femoral NerveIt is located inside the leg and supplies muscles that help in bending and straightening the leg. It supplies the adductor, gracilis and obturator externus muscles. The nervous system consists of the brain, spinal cord, and nerves.

The lateral femoral cutaneous nerve is a branch of the lumbar plexus, exiting the spinal cord between the L2 and L3 vertebrae. Depending on the direction of the signals they conduct, they are classified into afferent and efferent nerves. It runs obliquely along the side of the depression at the back of the knee joint to the head of the calf bone. The nervous system, essentially the body’s electrical wiring, is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. Nervous System 9. Young JZ. The nervous system derives its name from nerves, which are cylindrical bundles of fibers (the axons of neurons), that emanate from the brain and spinal cord, and branch repeatedly to innervate every part of the body. It runs through the neck, the armpit region and then into the arm. Motor neurons, on receiving signals from the central nervous system, bring about responses at the target organs. 62.17) is commonly known as squid. It is the only cranial nerve that emerges dorsally from the brain (near the back)…, The tibial nerve branches off from the sciatic nerve. Although the brain is the control center, its job would not be possible without the spinal cord, which is the major conduit for information traveling between brain and body. Nervous System 1.
