Chapter 7 Flashcards
Which type of muscle is under voluntary control
Skeletal
Which type of muscle is found in the heart
Cardiac
Which type of muscle is found in the blood vessels and airways ?
Smooth
Which muscle is attached to the bones
Skeletal
Which type of muscle does not have striations
Smooth
When a muscle increases in diameters is called
Hypertrophy
When a muscle begins to waste away because of disuse
Atrophy
Muscle - is partial contraction and resistance to stretching shown even when a muscle is at rest
Tone
Fibrous tissues that attach muscle to bones
Tendons
Attach bones to each other
Ligaments
Light meat vs dark meat chicken
Dark meat has a higher fat content and higher number of blood vessels which makes it dark
The two threadlike proteins (myofilaments) that slide to generate a muscle contraption are called
Actin and myosin
The thick myofilaments in a muscle cell are made of
Myosin
The thin myofilaments in a muscle cell are made up of
Actin
This substance stored in sarcoplasmic reticulum allows cross bridges to form between 2 types of myofilaments in muscle cells
Calcium
Energy molecule that functions in a muscle contraction to help promote the sliding process performed by myofilaments
ATP
Neurotransmitter released by nervous system opens sodium ion channels which allows sodium ions to excite muscle fibers
Acetylcholine
The point of - is the end of the muscle that is attached to a stationary bone
Origin
- is a test where a muscle group is stimulated with an electrical impulse that causes contraction
Electromyogram
Antagonist to the quadriceps , action
Hamstrings, when the quadriceps are contracted the hamstrings are stretched
The point of - is the end of the muscle that is attached to a moving Bone
Insertion
