Physiology Of The Muscular Tissue Flashcards
Muscles have what functions
Contractible
Extensible
Elastic
Three types of muscular tissues
Skeletal
Cardiac
Smooth muscles
What muscle tissue are voluntary
Only skeletal muscle
Example of involuntary muscle tissues
Smooth
Caridac muscle
Which is a voluntary muscular tissues
Smooth, skeletal , cardiac
Skeletal
Which muscle tissues have striations
Skeletal and cardiac
Muscle tissues with no striations
Smooth muscle
Muscle tissues with one nucleus
Smooth and cardiac
Muscle tissues with many nucleus
Skeletal
What is the only organ of the muscular system
Skeletal muscle
Skeletal muscle is how many % in males
40
Cardiac muscle is how many %
10%
Skeletal muscle is how many % in females
32%
Fascia surrounds
The entire skeletal muscle
Epimysium surrounds
Skeletal muscles and binds fascicles together.
It holds the fascicles together
Muscle fibers are arranged into bundles called
Fascicles
Permysium does what
It covers group of fascicles
Endomysium surrounds
It surrounds each muscle cell
Perymysium surrounds
It surrounds group of fascicles (muscle cells)
Satélite cell is for
Muscle regeneration
Aponeurosis
Fascia may connect muscle to muscle
Fascia connects muscle to muscle is called
Aponeurosis
Striations on skeletal muscles are due to
Arrangements of thick and thin filaments
A single muscle cell is called a
Muscle fiber
Fibers are made up of
Myofibrils
Fibers are made up of
Myofibrils
Myofibrils are made up of
Thick and thin filaments
Myofibrils are made up of
Thick and thin filaments
When muscle contracts calcium ion bonds to -
Troponin
Troponin does what
It exposes the binding site for the myosin cross bridge to attach to
The binding site for the cross bridge are located on
Actin
Calcium ions are released from ? To initiate muscle contraction
Sacroplasmic reticulum
When calcium ions are released from the Sacroplasmic reticulum to initiate muscle contraction and are reabsorbed upon muscle relaxation. What happens when calcium ions are not completely reabsorbed
The next muscle contraction would be greater than the previous muscle contraction
In order to make ATP in muscles, creatine phosphate transfers ? To ADp
Phosphate
Lactic acid is a by product of
Cellular respiration
Lactic acid is typically produced during
Anaerobic respiration
Correct sequence for the production of ATP for muscle contraction
CP, anaerobic respiration; Aerobic respiration
Functions of ATP in muscle contraction
Used to get the cross bridge to bind to actin
Used to get the cross bridge to disconnect from the actin
Lactic acid is produced during
Glycolysis
And anaerobic respiration
Which set of respiration produces the most ATP for muscle contraction
Aerobic
Which cells convert lactic acid back to pyruvic acid so that pyruvic acid can be used in producing ATP
Liver cells
Calcium triggers what
It triggers the binding of myosin to actin
What is a cross bridge
Where actin and myosin binds
The gap between a neuron and a muscle
Synaptic cleft
During full muscle contraction which region disappears
H region
