Coordination among Muscles Flashcards
What does the Arrangement of Fascicles mean for the Skeletal Muscle?
Fascicles can be arranged in different patterns.
This includes:
Parallel, Fusiform, Circular, Triangular and pennate.
What does the Arrangement of Fascicles mean for the Skeletal Muscle?
Fascicles can be arranged in different patterns.
This includes:
Parallel, Fusiform, Circular, Triangular and pennate.
What does the power of a muscle depend on?
It depends not on the length of the fibers but its Total Cross-Sectional Area.
What are the Skeletal Muscles Grouped into based on their movements at Joints?
They are arranged into groups called “Antagonistic” pairs at joints.
What are the Antagonistic Pairs of muscles groups called at joints?
They are in groups:
Flexors - Extensors
Abductors - Adductors
…
What is a Prime mover?
Within opposing Pairs a muscle called the prime mover Contracts to cause an action.
What is a Antagonist?
This is the Muscle within an Opposing pair that Stretches and yields to the effects to the prime mover.
What happens if the Prime mover and its Antagonist Contract at the same time with the same force what will happen?
There will be no movement.
What happens if the Prime mover and its Antagonist Contract at the same time with the same force what will happen?
There will be no movement.
Where are Synergist Mostly located?
They are usually located near a Prime mover.
What are “Fixators” and what is their purpose?
They Stabilize the Origin of the prime mover, This helps the prime mover work more efficiently.
What is a compartment of Skeletal Muscles?
In a limb a compartment is a Group of Skeletal muscles, their blood vessels and nerves Which all have a common function.
Within Fascicle Arrangement What are the types of Pennate?
This includes:
Unipennate, Bipennate & Muiltipennate.
What are the names for the Directions the muscles can go in?
Rectus, Transverse and Oblique.
What are the names that the Muscle can be categorized into relative to their size?
Maximus, Minimus, Longus, Brevis, Latissimus, Longissimus, Magnus, Major, Minor, Vastas.
What are the names that muscles can be categorized into Relative to their shape?
Deltoid, Trapezius, Serratus, Rhomboid, Orbicularis, Pectinate, Piriformis, Platys, Quadratus, Gracilis.
What are the names that muscles can be categorized into based on their Action?
Flexor, Extensor, Abductor, Adductor, Levator, Depressor, Supinator, Pronator, Sphincter, Tensor, Rotator.
What are the names that can be given to a muscle based on the number of Origins they have?
Biceps, Triceps, Quadriceps.
What do Synergist do?
They stabilize and contract the intermediate Joints.
What is an Example of a Fixator?
For Example the Scapula is a freely movable bone that acts as the origin for many arm muscles.
In Abduction of the arm the deltoid muscle is the Prime mover and the ( pecs, subclavius, traps, Serratus anterior ) act as Fixators.
What is a muscle with the name Rectus?
It means Parallel to the midline of the body.
What is a muscle with the name Transverse?
Perpendicular to the Midline.
