What is myofilament?
Myofilament are long tubular structures inside of muscle cells that are made up of shorter contractile sections called sarcomeres.
Tendons are structures in the body that perform which function?
Attach muscle to bone.
An electrical impulse moving down an axon is called?
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
Does increased muscle density mean more myofibrils per muscle fiber?
Yes, it means that you will gain more myofibrils per muscle fiber. A muscle fiber is a muscle cell, and everybody has about the same number. When you train your muscles, they will develop more myofibrils inside the muscle cells. So you cannot change the number of muscle fibers, or cells, but you can change the number of fibers, or myofibrils, inside them. The end result is more muscle density, not more muscle cells.
Where in the body is skeletal muscle found?
The skeletal muscle is all the voluntary striated muscle that is attached to bones throughout the body.
Are there more sodium ions inside or outside a cardiac muscle cell during the resting membrane potential?
Outside
What is myofilament?
Myofilament are long tubular structures inside of muscle cells that are made up of shorter contractile sections called sarcomeres.
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 are Long threadlike structures found in muscle fibers?
Myofibrils are thread like structures found in muscle fiber composed of bundles of myofilaments.
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 the muscles found in hollow structures?
smooth muscle
Which of the below structures is found in cardiac muscle tissue but not skeletal muscle tissue?
Intercalated discs
What are the structures within the muscle fiber that shorten to cause skeletal muscle fiber contraction?
Myofibrils
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.
Smooth muscle structures of the eyes?
The iris and the ciliary body
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.
