Joints or articulations (connections between bones) can be classified in a number of ways. The primary classifications are structural and functional. Functional classification is based on the type and degree of movement permitted. Types of Synovial Joints.jpg: Image of a skeleton and skematics of the different classes of synovial joints. Three Categories of Functional Joints
Nerve impulse. Definition. noun. (1) The movement of action potential along a nerve fiber in response to a stimulus (such as touch, pain, heat or cold). (2) The relaying of a coded signal that travels along a nerve cell membrane to an effector, such as muscle, gland or another nerve cell.Supplement. A nerve impulse is the relaying of a coded signal from a nerve cell to an effector (a muscle cell, a gland cell or another nerve cell) in response to a stimulus.It is the means by which a nerve cell communicates with another cell.erve impulse. Definition. noun. (1) The movement of action potential along a nerve fiber in response to a stimulus (such as touch, pain, heat or cold). (2) The relaying of a coded signal that travels along a nerve cell membrane to an effector, such as muscle, gland or another nerve cell.
Impulses that are sent along neurons are called action potentials. An action potential (also known as an impulse) is the electrical current that travels the length of an axon when a neuron has been stimulated. At rest the membrane inside of a neuron has a negative charge. This is called the resting membrane potential.. axon. The dendrites receive impulses from sensory receptors or other neurons and send them towards the cell body, which contains the nucleus. Impulses are then conducted along the axons full length away from the cell body to connect with the dendrites of another neuron, muscle, organ or gland of some kind.
