The human nervous system is a system of nerves that begins in the brain and is part of every area of your body from your fingertips to your eyes, from the skin on your toes to your bones, tendons and ligaments. There are two types of synapses found in the body: chemical synapses and electrical synapses. The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. 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.

Specialized cells detect stimuli from the 5 special senses: vision, hearing, balance, smell, and taste. The most well known reflex is the patellar reflex, which is checked when a physicians taps on a patient’s knee during a physical examination. 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. The nervous system allows for the almost instantaneous transmission of electrical impulses from one region of the body to another. Myelinated axons appear white due to the presence of lipids and form the white matter of the inner brain and outer spinal cord. Arrange the clues from hardest to easiest. I use them for warm up activities, homework assignments and preparation for the unit test. 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. In biology, the nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body.

Each axon is wrapped in a connective tissue sheath called the endoneurium. An exploration of the human body and its functions. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions inside and outside of the body and send this information to the CNS. Using this sensory information, it makes decisions about both conscious and subconscious actions to take to maintain the body’s homeostasis and ensure its survival. Individual axons of the nerve are bundled into groups of axons called fascicles, wrapped in a sheath of connective tissue called the perineurium.
