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.
3) motor neurons âcarry impulses from the brain and spinal cord to muscles or glands. The Response Mechanism. When a stimulus is received by a sensory neuron, the impulse (or message) is carried through fibrous extensions called dendrites to the cell body.he neuron, a nerve cell, is the functional unit of the nervous system that carries the impulse (the message) to the appropriate part of the nervous system or interprets the impulse and allows a response.
