Physiology Chap 13

Review muscle fibers

QuestionAnswer
Fasicle Bundle of Muscle Fibers
Tendon Connects Bone to Muscle
Aponeurosis Sheet like tendon
Sarcomere Unit bordered by z lines that contain Actin & myosin
Sarcolemma Cell membrane of a muscle cell
Actin Thin fibers involved in muscle contraction
Myosin Thick fibers involved in muscle contraction
Motor Neuron Nerve that innervates skeletal muscle
Motor Unit Muscle and nerve together
Calcium Attaches to Tropomin which slides Tropomyosin off of Actin
Sarcoplasmic Reticulum Stores calcium in skeletal muscle cells
T-Tubule Carries action potential deep inside muscle cell
Concentric Isotonic Movement
Eccentric Isotonic movement
Isometric No movement
Recruitment Increased # of Motor Units
Myoglobin makes red muscle red
Gap Junctions Single unit smooth muscle junctions
Intercollated Discs found in Cardiac Muscle
Striated & Several Nucleii Skeletal Muscle
ATP attached to... Mysoin heads
Neuromuscular Junction Axon & Muscle
Refractory Period Muscle loses its excitability
Latent Period Stimulus applied & muscle actual contraction
Action potential releases... Calcium from Sarcoplasmic Reticulum
Epimysium outermost layer surrounding muscle
Perimysium Surrounds each fasicle
Endomysium Surrounds each muscle fiber
Myofibril Proteins found in muscle fibers
z lines Borders between saccomeres
Smooth Muscle Autonomic, Non-striated, single nucleus, Calcium binds to Calmodulin
Multi Unit smooth muscle Individual cells that must each be stimulated
Single unit smooth Muscle gap junctions between cells, one action potential contracts all cells
Cardiac Muscle Striated, sarcomeres, involuntary, Autonomic
Intercollated Discs Thick fingerlike projections where gap junctions are lovated at the ends of the sarcolemma

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
