The lateral collateral ligament of the knee is on the outside of the joint, as indicated here: The meniscus is a c-shaped cartilage pad between the two joints formed by the femur and tibia. The meniscus acts as a smooth surface for the joint to move on.
Nerve cellsâalso known as neuronsâare the primary building blocks of the nervous system in humans and animals. On a fundamental level, a nerve cell functions by transmitting and receiving electrochemical messages.These messages can serve several purposes, including the transmission of sensory information to the central nervous system and the regulation and control of organs in the body.he three basic types of nerve cells are motor neurons, sensory neurons and interneurons. A motor neuron is a cell that transmits a signal to a muscle or gland.
The neuron (nerve cell) is the fundamental unit of the nervous system. The basic purpose of a neuron is to receive incoming information and, based upon that information, send a signal to other neurons, muscles, or glands.Neurons are designed to rapidly send signals across physiologically long distances.They do this using electrical signals called nerve impulses or action potentials.When a nerve impulse reaches the end of a neuron, it triggers the release of a chemical, or neurotransmitter. The neurotransmitter travels rapidly across the short gap between cells (the synapse) and acts to signal the adjacent cell.hey do this using electrical signals called nerve impulses or action potentials.
