Contraction and Stuff
Communication between the nervous system and skeletal muscle fiber occurs at this place.
What is the neuromuscular junction, also known as the myoneural junction?
Muscle mechanics include theses things.
The coordination, metabolism, and performance of skeletal muscle?
Cardiac is muscle is also known as this
What is cardiocytes?
After a contraction, a muscle fiber returns to its original length through a combination of these things.
What is elastic forces, opposing muscle contractions, or gravity?
The four lobes of the brain.
What are the temporal lobe, the parietal lobe, the occipital lobe and the frontal lobe?
Release of acetylcholine from the synaptic terminal can result in changes that result in this event.
What is skeletal muscle contraction?
A single stimulus-contraction-relaxation sequence in a muscle fiber.
What is a twitch?
Smooth muscle regulates movement along internal passage ways in the digestive and urinary systems by this type of muscle
What is sphincters (circular muscle)?
After the action potential has ended, these many things occur in order for the sarcoplasm to return to resting normal levels.
What is two?
The longest bone in an adult human.
What is the femur?
As long as calcium ions and ATP remain available, this continues.
What is a contraction cycle?
A muscle producing peak tension during rapid contraction/relaxation is said to be in this stage.
What is incomplete tetanus?
This difference between cardiac muscle tissue and skeletal muscle is this shape
What is short and broad and no triads in cardiac muscle?
With the decrease of calcium ion concentrations in the sarcoplasm fall, these steps occur.
What are calcium ions detach from troponin, troponin returns to its original position, the active sites are covered by tropomyosin?
A disease in which bones lose an excessive amount of protein and minerals and consequently lose bone mass.
What is osteoporosis?
The binding of calcium ions to troponin exposes the active sites of these filaments.
What is thin?
This occurs by increasing the rate of stimulation until the relaxation phase is eliminated.
What is complete tetanus?
Contraction is based on calcium interacting with calmodulin, a calcium binding protein.
What is the functional difference of smooth muscle compared to skeletal muscle?
The amount of tension generated during a contraction depends on the number of this interaction.
what is cross-bridge interactions that occur?
The circulation of blood between the heart and lungs.
What is pulmonary circulation?
This is the link between the generation of an action potential in the sarcolemma and the start of a muscle contraction.
What is excitation-contraction coupling?
When a calcium ion is released, it is released at all the triads in the muscle fiber causing all the myosin heads in the zone of overlap to interact with the thin filament.
What is the all-or-none principle?
These connections help stabilize the position of adjacent cells and maintain the three dimensional structure of the tissue.
What are intercalated discs?
The number of cross-bridge interactions depend on the amount of overlap in theses filaments.
What are thick and thin filaments?
A tubular projection attached to the large intestine that is located at the lower right side of the abdomen.
What is the appendix?
