Muscle Tissue
What connects muscle to bone?
Tendon
The connection between a motor neuron and a muscle cell is called a
Neuromuscular junction
Which muscle group is found on the anterior thigh?
Quadriceps
Thick filaments are composed of
Myosin
These muscles are non-striated and involuntary.
Smooth muscles
What is the contractile unit of a muscle fiber?
Sarcomere
Which neurotransmitter crosses the synapses of a neuromuscular junction?
Acetylcholine (Ach)
The four muscles of the rotator cuff are
Supraspinatus
Infraspinatus
Teres minor
Subscapularis
The movement of actin along the length of myosin during muscle contraction is described as the
Sliding filament theory
These muscles are identified because of the presence of intercalated discs.
Cardiac
Individual muscle sections that combine to form a fascicle are called
Myofibrils
Motor end plate
Linea alba
A single neuron stimulating a number of muscle fibers comprises a
Motor unit
Smooth muscles
Skeletal muscle is classified as
Striated and voluntary
A combination of a T-tubule with sarcoplasmic reticulum cisternae on either side make up a
Triad
Knee flexion
What two small proteins are found wrapped around actin?
Troponin and tropomyosin
Which muscle type has multiple nuclei and mitochondria?
Skeletal
Which layer of tissue surrounds a fascicle of muscle fibers?
Perimysium
The electrical conduction through the T-tubule causes the release of what molecule from the sarcoplasmic reticulum?
Calcium
The temporalis and masseter are muscles used for what digestive process?
Chewing (Mastication)
The binding, then release, of what molecule allows for contraction of the sarcomere?
ATP
A muscles that opposes the action of another muscle is called a
Antagonist
