Acetylcholine is the chemical that crosses the synapse causing a muscle to contract. It is released due to an electrical impulse sent from your brain down your nervous system.

What is the source of chemical enegry used to power a muscle cell in your arm?
ATP is the source of chemical energy used to power a muscle cell in your arm.
What cell of the human body has more mitchondria a muscle cell or skin cell?
A muscle cell
Which answer best explains why certain patterns of chemical modifications of histone proteins could influence whether a cell became a muscle cell or a brain cell?
They could affect which sets of genes are transcribed in different cell types.
Which method does potassium enter the cell?
Special sites on the cell unlock to allow the glucose to enter. This is triggered by the presence of a chemical called insulin.
Which cell has more mitochondria a muscle cell or a skin cell?
Muscle cells have thousands more mitochondria.
What are the 4 stages of a muscle cell?
Tonus (relaxation), Excitation (neural stimulation, Clonus (contraction), Tetanus (prolonged contraction), return to Tonus (relaxation) Or Excitation, Excitation-Contraction Coupling, Contraction, Relaxation
What is the source of chemical enegry used to power a muscle cell in your arm?
ATP is the source of chemical energy used to power a muscle cell in your arm.
What chemical binds to the muscle cell memebrane causing a temporary rush of what into the muscle cell?
Sodium ions
What maintains a chemical balance within a cell by regulating the materials that enter and leave the cell?
The Plasma membrane regulates what enters and exits the cell.
What chemical into the muscle cell membrane causes a temporary rush?
Acetylcholine (ACh)
Immediately following the arrival of the stimulus at a skeletal muscle cell is a short period called the ------------ period during which the events of excitation-contraction coupling occur?
latent period
What structure is responsible for the excretion of most cellular wastes?
Smooth muscle surrounding the bladder pushes urine out of the urethra.
What part of a plant cell the cell wall or the cell membrane what enters or leave the cell?
The cell membrane controls what enters or leaves the cell.
What is chemical work within cells powered by?
The contraction of a muscle cell is an example of mechanical work.
What are facts about a skeletal muscle cell?
A skeletal muscle cell is a cell of a skeletal muscle.
Which of 2 chemicals listed would be good skeletal muscle relaxant and why chemical A binds to and blocks ACh receptors of muscle cells and Chemical B floods the muscle cells cytoplasm with CA2 plus?
Chemical A would be the best muscle relaxant. Since the muscle relies on ACH as a stimulant, this chemical would inhibit communication between the muscle cell and the neuron thus making it not contract. While Chemical B would cause further contraction of the muscle since calcium is needed to help the myosin head to attach to the actin filliment which creates muscle contraction.
What is a muscle cell?
A muscle cell is a cell which can change length
