Leg Muscle Anatomy 1
The hamstrings (posterior thigh) are made of three muscles. The Semimembranosus, semitendinosus, and the ____________.
What is the Biceps femoris?
The beginning of a muscle
What is the origin?
The myofilament made of actin
What is thin filament?
The amount of energy required to raise the temperature of 1 gram of water 1 degree.
What is a calorie?
Type of muscle found in your heart.
Cardiac muscle
The muscle on your anterior thigh found most laterally.
What is the Lastus lateralis?
Muscle that opposes the movement of another muscle.
What is an antagonist?
Structure that pulls the actin filament toward the center of the muscle fiber.
The value is used to calculate calories burned during exercise. (Not the acronym)
What is MET? (Metabolic Equivalent Task)
Requires oxygen and occurs in the mitochondria
Aerobic
The largest calf muscle found most superficially on the posterior side of your lower leg.
What is the gastrocnemius?
Resistance.
Responsible for twisting tropomyosin away from the active site.
What is troponin?
A total or summation of the Active Energy Expenditure and the Resting Energy Expenditure.
What is Total Energy Expenditure?
Type of muscle that performs anaerobic respiration and us only used for short periods of time.
What is fast twitch?
The muscle is responsible for flexing your toes.
Extensor Digitorum Longus
If a muscle fiber contracts, that entire fiber will contract; there is never partial contraction of a singular muscle fiber.
What is the All-or-nothing principle?
Responsible for breaking the bond between the myosin head and the active site to end the muscle contraction.
What is ATP?
MET is equivalent to calories divided by a person's weight (kg) times the _______.
What is the amount of time exercising?
Provide oxygen and nutrients to the muscles for ATP production.
What are blood vessels?
The deltoid is this type of muscle during the flexion of the arm, by providing support to the origin of the biceps brachii. Be specific.
What is Fixator?
Responsible for coordinating the contraction of muscle fibers within a myofibril by forming passages throughout the muscle fiber.
What are the T-Tubules?
A person's TEE is 1,265 calories/day. In order to lose weight they only eat 1,000 calories/day. This is a ______ ___________.
What is caloric deficit?
Characteristic of muscle cells (fibers) that means to have many nuclei.
What is multinucleate?
