Glycogen is stored mainly in the liver, but the skeletal muscles and glial cells in the brain also contain a small amount of glycogen. The amount of glycogen stored in the liver is about 10 percent of its mass.
Although the amount of glycogen stored in muscles is only about 1 percent of their mass, muscle tissue contains about twice the amount of glycogen that the liver does because the amount of muscle mass in the body surpasses the mass of the liver.
Glucose, a major source of bodily fuel, is stored in the form of glycogen. Excess glucose can be converted into glycogen, the storage form of glucose in animals. When the body senses a need for more glucose, the hormone glucagon is released and acts on the liver to convert glycogen back to glucose for use.Learn More
Nervous tissue is found in peripheral nerves throughout the body and in the organs of the central nervous system, the brain and spinal cord. Nerve tissue is composed of neurons, which are specialized cells able to react to stimuli by sending a signal down a long strand of cell known as an axon. Nervous tissue is responsible for receiving information from the senses, processing it and sending out instructions.Full Answer >
Touch receptors are receptors on the external part of the body that relay messages to the brain about tactile sensations in the environment. Touch receptors may be categorized as mechanoreceptors or chemoreceptors.Full Answer >
Glycogen is a polysaccharide that is the storage form of glucose in the human body. Glucose is an important biomolecule that provides energy to cells throughout the entire human body. Humans derive glucose from the foods that they eat. When they are running low on glucose, glycogen can be utilized as a glucose source.Full Answer >
