Muscle Tissue
Muscle tissue found only in the heart
What is cardiac?
Epimysium in a muscle comes together to form this.
What is a tendon?
The cell of a muscle is known as this.
What is a myocyte?
A nerve impulse is sent to the muscle via this.
What is a lower motor neuron?
Calcium binds to this fiber
What is actin?
Muscle connected to the skeleton.
What is skeletal?
Groups of myocytes are called this
What are fasciculi?
Plasma membrane covering of the fiber.
What is the sarcolemma?
This neurotransmitter is triggered when the impulse hits the muscle.
What is ACh?
Myosin heads are energized via this energy component.
What is ATP?
The muscle tissue found within hollow organs.
What is smooth?
Connective tissue surrounding bundles of 10-100+ fibers
What is the perimysium?
Cytoplasm of the muscle fiber containing many mitochondria.
What is the sarcoplasm?
What does ACh open in the muscle?
What are ion channels?
Myosin heads and actin fibers join together to form this.
What is a crossbridge?
Muscle tissue that looks to have lines running through it. Skeletal and cardiac are classified as this.
What is striated?
Connective tissue surrounding each individual fiber.
What is endomysium?
This area of the sarcoplasm is a storage area for Ca2+.
What is the sarcoplasmic reticulum?
This rushes in as the ion channels open.
What is Na+ (sodium)?
All myofibrils can be activated at once because of this
What is the T tubule system?
Skeletal muscle is the only muscle type that is this.
What is voluntary?
A rich blood supply is important for one of two reasons (only need one).
What is Mass production of ATP and/or Removal of Waste?
Daily Double!! Ca2+ is vital to muscles for this reason.
What is for muscle contractions?
This is released once the Na+ rushes in.
What is calcium?
The T tubule system is derived from this.
What is smooth endoplasmic reticulum?
