Muscle fibre arrangement of the orbicularis oris muscle
What is circular?
The names of the three types of muscle
What is skeletal, cardiac and smooth?
The names of the three layers of muscle from innermost to outermost
What is endomysium, perimysium, and epimysium?
This plane divides the body into a right and left half
What is the sagittal plane?
Muscle fibre arrangement of the biceps brachii muscle.
What is parallel?
The only muscle type that has multinucleated cells
What is skeletal?
Where calcium is stored in a muscle fibre
What is the sarcoplasmic reticulum?
Type of epithelial tissue consisting of two or more layers of cells
What is stratified?
Muscle fibre arrangement of the pectoralis major muscle
What is convergent?
Type of muscle that has short, striated and branched cells connected by intercalated disks
What is cardiac?
Extensions of the sarcolemma responsible for transmitting action potentials into the muscle cell
What are transverse tubules?
Type of cartilage that makes up intervertebral discs
What is fibrocartilage?
Muscle fibre arrangement of the deltoid muscle
What is multipennate?
Type of muscle that has short, nonstriated, and spindle-shaped cells
What is smooth?
The plasma membrane of a muscle fibre
What is the sarcolemma?

What is syndesmosis?
Muscle fiber arrangement of the rectus femoris muscle
What is bipennate?
Type of muscle found in the walls of inner organs
What is smooth?
The six steps in the sliding filament theory in order from start to finish
What is...
1.contraction cycle starts (release of calcium ions)
2. active site exposure (move tropomyosin)
3. cross-bridge formation (myosin heads to thick filaments)
4. myosin head pivoting ("power stroke")
5. cross-bridge detachment; myosin reactivation (ATP helps return myosin to its relative position)
The cells that are responsible for bone resorption and destruction
What are osteoclasts?
