Overall, the spinal cord is an essential part of the nervous system, responsible for relaying information between the brain and the rest of the body, as well as for the processing of reflexes. For example, if you accidentally touch a hot stove, the reflex arc of the spinal cord will automatically cause you to pull your hand away before the brain even registers the pain. The spinal cord is also responsible for the processing of reflexes, which are automatic responses to certain stimuli. Pairs of nerves emerge at intervals along the spinal cord, and these nerves are responsible for carrying sensory information from the body to the CNS, and motor information from the CNS to the body. It is located inside the vertebral column, a bone structure along the back. The spinal cord is a long, thin, tubular structure of nervous tissue that is part of the central nervous system (CNS). It makes up the internal musculature of organs like the uterus and digestive system. Smooth muscle is a type of muscle that contracts automatically and slowly. The two main types of reflexes are somatic reflexes and autonomic reflexes. Examples include breathing and heart rate control. Reflexes controlled by this system are called autonomic reflexes, which affect inner organs. It is not under voluntary control and controls subconscious actions. The autonomic nervous system carries nerve impulses to glands, smooth muscle, and cardiac muscle. These reflexes affect muscles, like moving your leg when you step on something sharp. It is also called the somatic nervous system, and the reflexes it controls are called somatic reflexes. The voluntary nervous system carries nerve impulses from the CNS to muscle effectors, and is under conscious control. The motor nervous system, which regulates muscle movement, is made up of two categories: the voluntary nervous system and the autonomic nervous system. For example, a muscle contracts to move a hand away from a hot plate. An effector is a body part or cell that responds to the information conveyed by the receptor. Motor neurons carry nerve impulses away from the central nervous system to effectors.Ī receptor is an organ or cell that detects a stimulus, like a change in temperature, and sends that information somewhere else in the body. Sensory neurons carry nerve impulses from receptors to the central nervous system. The peripheral nervous system further divides into sensory and motor neurons. The central nervous system (CNS) includes the brain and spinal cord, while the peripheral nervous system (PNS) is made up of nerve pairs that come from the brain or spinal cord. The nervous system is divided two main parts, each with its own systems. ![]() In this article, we'll explore different types of reflexes. Our hand moves away from the plate to avoid getting burned. ![]() This reflex kicks in when we touch something too hot, like a hot plate. There are many types of reflexes, but one we use often is the protective reflex. They happen without us even thinking about it. Reflexes are automatic reactions our body makes when something triggers them.
