The ligament of the ankle that connects the lateral talus and fibular malleolus, preventing anterior displacement of the talus in the mortise. This ligament is injured with an excessive inversion and plantar flexion motion (supination) and is the most commonly injured ligament of the ankle.eriodontal ligament the fibrous connective tissue that surrounds the root of a tooth, separating it from and attaching it to the alveolar bone, and serving to hold the tooth in its socket. It extends from the base of the gingival mucosa to the fundus of the bony socket.
This gap between the two cells is called a synapse. Impulses are carried across a synapse by chemical messengers called neurotransmitters. Approximately 30 different neurotransmitters have been identified, but they all do one of two things: Stimulate the action potential in the next neuron cell.Speed up the impulse.Inhibit the action potential in the next neuron.mpulses move from one nerve cell to another because of a difference in electrical action potential caused by ions inside and outside the cell. The cell membrane is selectively permeable to potassium ions, K + , and highly impermeable to sodium ions, Na + .
Quick rise and fall of the a cell's electrical membrane potential, in oder to make an electric impulse travel; from the moment the impulse enters the neuron through a dendrite to the moment it leaves through the axon to go to another neuron. Chemical Synapse. How does a nerve impulse travel.
