what is the minimum stimulus that can contract a muscle fiber?
which stimulus can contract all muscle fibers in a muscle
what is the name for the rule of the contraction of a muscle fiber?
All or none
If a muscle is stimulated with a threshold stimulus, it will contract completely. - What is this phenomenon called? .
all or none phenomenon
Contraction of a whole muscle is called?
graded contraction is?
contraction of a whole muscle is graded, which means the more muscle fibers inside a muscle get contracted, the muscle gets more contracted
energy for the contraction of a muscle directly comes from ATP. ~ this is called?
energy of contraction
Storage of energy in the muscle is called?
Energy in the muscle depends on which factor?
How to make ATP?
through the process of cellular respiration.
C6H12O6 + O2 -> H2O + CO2 + ATP
the chemical reaction of cellular respiration
ATP comes from energy stored in?
high energy bonds of Glucose
if we want to have energy from 1 molecule of the glucose then we need?
6 oxygen, 6 water, 6 carbon dioxide, 36 atp from the cellular respiration chemical reaction
when making ATP, glucose breaks down how many pyruvic acids?
2 pyruvic acids
In the Anaerobic phase, the 2 pyruvic acids will turn into?
6O2 6H20 6CO2 -> 34 ATP
Large storage of O2 is called?
Hemoglobin, inside of the RBCs
what is the small storage of the oxygen in the muscle?
what is the large storage of the oxygen in the blood?
Hemoglobin, inside of the Red Blood Cells.
the stationary muscle attachment is the?
origin of the muscle
the movable attachment is the?
Insertion of the muscle
the insertion works with what of the muscle
with the origin
which Contraction refers to the pressure in the muscle that stays the same. length of the muscle is changing?
length of the muscle stays the same, and pressure in the muscle changes. Lifting. Increases the action of actin and myosin, muscles get bulky; this contraction is called?
responsible for muscle tone. Come from a little Ach that is constantly released in the muscle is what type of contraction?
temporalis is considered as what type of muscle?
masseter is considered as what type of muscle?
facial expression muscles are?
frontalis, occipitalis, epicranial aponeurosis
compresses cheeks inward
elevates eyebrows and wrinkles forehead
pulls scalp posteriorly
