How do electrolytes play a role in muscle contraction?
Electrolytes help regulate the electrical impulses that control muscle contractions. They maintain the balance of fluids inside and outside of muscle cells, allowing for proper muscle function. When muscles contract, electrolytes like sodium, potassium, and calcium are essential for transmitting signals between nerve cells and muscle cells.
Which tissue has intercalated discs?
Cardiac muscle tissue has intercalated discs, which are specialized structures that help with communication and coordination of muscle contractions in the heart.
How do T-tubules contribute to the contraction of muscle fibers?
T-tubules are structures in muscle cells that help transmit electrical signals for muscle contraction. They allow for the rapid spread of these signals throughout the cell, ensuring coordinated muscle fiber contraction.
What is myofilament?
Myofilaments are the protein fibers within muscle cells that slide past each other to cause muscle contractions. There are two main types of myofilaments: thin filaments, made up of actin protein, and thick filaments, made up of myosin protein. The interaction between these two types of filaments is essential for muscle contraction.
What is correct order of osseous structures from largest to smallest?
The order of structures of the human body from smallest to largest are:cellgroups of specialized cells make a certain type of tissue, for example, muscle tissuea group of alike tissues make up an organa group of organs that all have a similar function make up an organ systemall of the organ systems make up the organism, e.g. the human body
Are there more sodium ions inside or outside a cardiac muscle cell during the resting membrane potential?
Outside
What is the difference between inside and outside skirt steak?
The main difference between inside and outside skirt steak is their location on the cow. Inside skirt steak comes from the diaphragm muscle inside the rib cage, while outside skirt steak comes from the plate section of the cow. Inside skirt steak is typically more tender and has a more uniform thickness, while outside skirt steak is known for its intense beefy flavor but can be tougher.
What muscle is in the upper arm?
There are two main ones, the tricep and the biscep. The tricep bicep is on the inside angle as defined by your elbow, the tricep is on the outside.
What are Long threadlike structures found in muscle fibers?
Myofibrils are thread like structures found in muscle fiber composed of bundles of myofilaments.
What are the shared structures in nerve muscle epithelial bone cells?
The shared structures between nerve, bone, epithelial, and muscle cells is that they share reproduction structures and the same blood type.
What is depolarizing?
loss of polarization; especially : loss of the difference in charge between the inside and outside of the plasma membrane of a muscle or nerve cell due to a change in permeability and migration of sodium ions to the interior
What compound stored oxygen inside skeletal muscle cells?
keratinThe correct answer is NOT keratin... the correct answer is myoglobin. This is the oxygen-binding pigment in muscle.
Does muscle covers the outside of your body?
Skin covers the outside of your body, which, because of its makeup, is closer to an organ than a muscle.
What are the muscles found in hollow structures?
smooth muscle
Can you get tongue cramp?
No you can't crack your tongue. Your tongue is a muscle and does not have any bones inside it. Since it's a muscle, it's possible that you could strain or injure it. You could also pull or tear the structures that attatch your tongue to the floor of your mouth.
Which of the below structures is found in cardiac muscle tissue but not skeletal muscle tissue?
Intercalated discs
What is smallest muscle in the human?
the stapedius muscle inside the ear
