Small tree-like structures called dendrites extend from the cell body to pick up stimuli from the environment, other neurons, or sensory receptor cells. Together, these organs are responsible for the control of the body and communication among its parts. CSF absorbs shocks between the brain and skull and between the spinal cord and vertebrae. It also supplies a part of the skin of the thigh, hip and knee joints. Supports over 40+ diagram types and has 1000’s of professionally drawn templates. Oculomotor, trochlear, and abducens nerves (III, IV, and VI) all work together to allow the brain to control the movement and focus of the eyes. The vagus nerve (X), sometimes called the wandering nerve due to the fact that it innervates many different areas, “wanders” through the head, neck, and torso. Well, we're looking for good writers who want to spread the word. Integration. It is mandatory to procure user consent prior to running these cookies on your website. The brain is the seat of consciousness and determines who we are as individuals. We use cookies to give you a great browsing experience. Because neurons are extremely specialized cells that are essential to body function and almost never reproduce, neuroglia are vital to maintaining a functional nervous system. It extends from the brain up to the space between the first and the second lumbar vertebrae. Pudental NerveOriginating in the sacral region of the spinal cord, it is formed from the second, third and fourth sacral nerves. The brain and spinal cord form the control center known as the central nervous system (CNS), where information is evaluated and decisions made. The dermatomes and spinal nerve posters are also popular with physiotherapy students. The tibial nerve generally…, The maxillary nerve is a nerve located within the mid-facial region of on the human body. Sometimes this is the result of diseases like Alzheimer’s and Parkinson’s disease. It passes through psoas major, where it supplies some smaller motor branches. 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. The median nerve is the only nerve passing through the carpal tunnel. Reading this article will be like reading about the human nervous system from your science textbook as this article carries a labeled human nervous system diagram to help you understand its design and working. It was wonderful to pick up the intricacies of a seemingly boring subject like human anatomy from her. Individual axons of the nerve are bundled into groups of axons called fascicles, wrapped in a sheath of connective tissue called the perineurium. Synapses may form between 2 neurons or between a neuron and an effector cell. is done on EduRev Study Group by Class 10 Students. Would you like to write for us?

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. Flowchart illustrating the human nervous system. Sign up to receive the latest and greatest articles from our site automatically each week (give or take)...right to your inbox. What are known as the special senses—vision, taste, smell, hearing, and balance—are all detected by specialized organs such as the eyes, taste buds, and olfactory epithelium. It was the skeletal system diagram that helped me understand the “skeleton” of human bodies. Saphenous NerveIt is the largest cutaneous branch of the femoral nerve. Free nerve endings are simply free dendrites at the end of a neuron that extend into a tissue. Each of the special senses has its own unique sensory cells—such as rods and cones in the retina to detect light for the sense of vision. Reflexes are fast, involuntary responses to stimuli. inc VAT, Now It is through the peripheral nervous system. Neuroglia, also known as glial cells, act as the “helper” cells of the nervous system. Brachial PlexusThe arrangement of nerve fibers formed by the ventral rami of the lower cervical and upper thoracic nerve root, precisely between the nerve roots of the 5th cervical and 1st thoracic vertebra, is known as the brachial plexus. The nervous system can be a complicated topic of study, but this nervous system mind map example clarifies how various parts of the nervous system relate to one another. Nervous System Central Nervous System (CNS) (Brain & Spinal Cord) Peripheral Nervous System (PNS) (Cranial & Spinal Nerves ) Sensory Division (Afferent) Motor Division (Efferent) Voluntary or Somatic Nerves Involuntary or Au tonomic Nerves Sympathetic Parasympathetic Nervous System Flow Chart . Myelination speeds up the movement of APs in the axon by reducing the number of APs that must form for a signal to reach the end of an axon. These neurons can only send information one way. Some of its larger branches run through the pelvic area. How does the central nervous system communicate with the other body organs? 974 2703 05. You must have JavaScript enabled in your browser to utilize the functionality of this website. Company Registration No. The signals are transmitted in the form of electrochemical waves or chemicals. 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. 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.
