Saltatory conduction is present in myelinated<\/p>\n\n\n\n
Sarcolemma definition
The fine transparent tubular sheath which envelops the fibers of skeletal muscle<\/p>\n\n\n\n
When initiating a nerve conduction, a sodium channel is opened to allow sodium to influx into the cell. As sodium enters the cell, it depolarizes the cell (creating a change in the electrical charge of the membrane), allowing for the cell to creamy a graded potential. Once the signal reaches the axon hillock or axon of the cell, this will allow for _<\/em><\/strong><\/em><\/strong> channels found on the axon hillock or axon of the cell to flood the cell with more sodium ions and allow the continued propagation of the electrical signals down the neuron.

Which of the following property of muscle tissue means the ability to be stimulated to be shortened or contracted?
A. Extensibility
B. Elasticity
C. Contractility
D. Hyperplasia
C. Contractility<\/p>\n\n\n\n
Sarcoplasmic reticulum definition
A specialized form of the endoplasmic reticulum of muscle cells (necessary for muscle contraction and relaxation)<\/p>\n\n\n\n
