A muscle with origin from the lateral border of the tuberosity of the ischium
, with insertion into the intertrochanteric crest, with nerve supply from the sacral plexus, and whose action rotates the thigh laterally.
What is the correct definition of voluntary muscles?
A voluntary muscle is
a muscle that you choose to move
, like those in the arms and legs, as opposed to the ones that move automatically, like the heart. Muscle is the tissue in animals that produces movement or motion. Voluntary means done out of free will or by choice.
What is an example of quadrate muscle?
The biceps and hamstrings are examples of fusiform muscles. … Another type of muscle is the quadrate muscle-
quadratus lumborum
, quadratus femoris to name a couple. Quadrate muscles are stabilizers along with whatever other function they perform. The rhomboids are a quadrate muscle.
What is a triangular muscle?
A flat muscle with a broad origin and narrow insertion
.
What is a Multipennate muscle?
Definition: A pennate muscle (also called a penniform muscle) is a muscle with fascicles that attach obliquely (in a slanting position) to its tendon. … If
the central tendon branches within a
pennate muscle, the muscle is called multipennate, as seen in the deltoid muscle in the shoulder.
What is the strongest muscle shape?
The strongest muscle based on its weight is
the masseter
. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars. The uterus sits in the lower pelvic region.
What is an example of a Unipennate muscle?
In a unipennate muscle, the fascicles are located on one side of the tendon.
The extensor digitorum of the forearm
is an example of a unipennate muscle. … A common example is the deltoid muscle of the shoulder, which covers the shoulder but has a single tendon that inserts on the deltoid tuberosity of the humerus.
Is the heart a voluntary muscle?
Cardiac muscle differs from skeletal muscle in that it exhibits rhythmic contractions and
is not under voluntary control
. The rhythmic contraction of cardiac muscle is regulated by the sinoatrial node of the heart, which serves as the heart’s pacemaker.
Which out of the following is a voluntary muscle?
Voluntary muscles include
biceps, triceps, thigh muscles
, etc. Complete answer: There are three kinds of muscles in our body that conduct the body’s various activities. Skeletal muscles, cardiac muscles and smooth muscles are these three types of muscles.
What are the 3 types of voluntary muscles?
The three types of muscles in the body include
skeletal muscle
, smooth muscle, and cardiac muscle.
Which is the most common type of muscle?
Skeletal muscle tissue
is the most common type of muscle tissue in the human body. By weight, an average adult male is about 42 percent skeletal muscles, and the average adult female is about 36 percent skeletal muscles.
What are the two points of attachment for muscles?
Muscle Anatomy. All muscles exert their force by pulling between at least two points of attachment. The movement that results from contraction is called the action of the muscle. Typically, one attachment remains stationary and is called
the origin
and the other attachment moves and is called the insertion.
Where is the largest muscle in the body located?
The largest muscle in the body is the gluteus maximus. Located
at the back of the hip
, it is also known as the buttocks. It is one of the three gluteal muscles: medius.
What is an example of a Multipennate muscle?
A type of pennate muscle wherein the diagonal muscle fibers are in multiple rows with the central tendon branching into two or more tendons. Example of multipennate muscle is
deltoid muscle
.
What does Bipennate mean?
Medical Definition of bipennate
:
having the fibers arranged obliquely and inserting on both sides into a central tendon The biceps brachii
is a bipennate muscle with two heads of origin.—
Are Pennate muscles the strongest?
Because these muscles are so long, individual muscle fibers don’t extend the entire length of the muscle. … Thus, if two muscles were of equal cross-sectional area, a pennate muscle
would be stronger than a parallel fibered one
because of its larger physiological cross-sectional area.
