Question 1

The functional unit of the muscle is called the
A)Osteon
B)Nephron
C)Sarcomere
D)Trabebulae

Accepted Answer

The sarcomere is the functional unit of the muscle, consisting of actin and myosin filaments that contract to produce movement. Option A (osteon) is a structural unit of bone tissue, option B (nephron) is a functional unit of the kidney, and option D (trabeculae) are thin, branching fibers within certain tissues and organs, such as the spongy bone in the human body.

Question 2

Accepted Answer

Striated refers to the presence of stripes or bands, particularly in muscle tissue. The term rhabd/o specifically refers to striated muscle tissue.

Question 3

Surgical removal of a tendon
A)Tenidoectomy
B)Tenioectomy
C)Tenosiectomy
D)Tenonectomy

Accepted Answer

The correct term for the surgical removal of a tendon is tenonectomy. The other options have misspellings or incorrect suffixes.

Question 4

A muscle with poor or weak tone is best termed.
A)Atony
B)Pretonia
C)Dystonia
D)Polytonia

Accepted Answer

The answer of A muscle with poor or weak tone...

Question 5

The process of recording muscle action.
A)Myogram
B)Myograph
C)Myography
D)Musculoglobulin

Accepted Answer

Myography is the process of recording muscle action, typically involving the use of a device or technique to measure and record the force and movement of muscles.

Question 6

The interspinales muscles are long slender muscles, 'inter' means
A)Inside
B)Between
C)Over the top
D)Under the layer

Accepted Answer

The prefix "inter-" means between, so the correct answer is B) Between.

Question 7

The sartorius muscle received its name because this action was common to
A)Tailors
B)Sailors
C)Meat cutters
D)Trumpet players

Accepted Answer

The sartorius muscle is named after the Latin word "sartor," which means a tailor. This muscle helps to cross the legs in a seated position, which is a common action for tailors.

Question 8

Which of the following initial sets reflects the ability of a patient to accomplish daily tasks?
A)CPK
B)PEM
C)ACh
D)ADLs

Accepted Answer

ADLs stand for activities of daily living, which include tasks such as bathing, dressing, eating, and toileting. These tasks are important measures of a patient's functional ability and ability to live independently, making it the best initial set to reflect their ability to accomplish daily tasks. CPK (creatine phosphokinase) measures muscle damage, PEM (protamine exchange measure) measures clotting ability, and ACh (acetylcholine) is a neurotransmitter important in muscle function and memory.

Question 9

A muscle group that aids in the action of another muscle is called
A)Aponeurosis
B)Antagonist
C)Synergist
D)Atony

Accepted Answer

A muscle group that aids in the action of another muscle is called a synergist. A synergist helps the agonist muscle by stabilizing the joint or assisting the agonist in its movement. An antagonist refers to a muscle that causes the opposite movement of the agonist, while aponeurosis is a sheet of connective tissue that attaches muscle to bone or muscle to muscle. Atony refers to the lack of muscle tone or strength.

Question 10

A multipennate muscle will have ________ feather(s).
A)one
B)two
C)three
D)many

Accepted Answer

A multipennate muscle is characterized by having multiple feather-like branches or fascicles attaching to a central tendon. These fascicles in turn have their own subdivisions or feather-like branches, resulting in a highly branched and intricate structure. Therefore, a multipennate muscle will have many feathers or subdivisions.

Question 11

The extensor digitorum muscles will
A)Bend a finger
B)Straighten a finger
C)Move finger outward
D)Move the finger to center

Accepted Answer

The extensor digitorum muscles are responsible for straightening the fingers.

Question 12

The SCM muscle will rotate the ________.
A)Hip
B)Neck
C)Thumb
D)Shoulder

Accepted Answer

The SCM muscle (sternocleidomastoid) is located in the neck and is responsible for rotation of the head.

Question 13

Inability to coordinate muscle motion, 'no order'
A)Asterixis
B)Clonus
C)Ataxia
D)Atony

Accepted Answer

Ataxia is the term used to describe the inability to coordinate muscle motion, resulting in seemingly random and uncontrolled movements. Asterixis refers to a flapping tremor in the hands and is often seen in liver failure. Clonus is a repetitive, rhythmic contraction of a muscle that is often seen in neurological disorders. Atony is a lack of muscle tone or strength.

Question 14

Which of the following prefixes is best to describe 'over development of the muscle'
A)Sub
B)Ecto
C)Apo
D)Hyper

Accepted Answer

"Hyper" means excessive or over, making it the best choice to describe the over development of a muscle.

Question 15

Herbert sustained a deltoid injury last week. He injured his _________.
A)Hand
B)Knee
C)Shoulder
D)Acetabulum

Accepted Answer

The deltoid is a muscle located in the shoulder, so the correct answer is C.

Question 16

The suffix meaning 'strength'
A)rrhexia
B)sthenia
C)cele
D)ity

Accepted Answer

The suffix "-sthenia" means strength, as seen in words like "asthenia" (lack of strength) and "hypersthenia" (excessive strength).

Question 17

Correct spelling for a 'painful muscle condition without weaknesses'
A)Fibromyosia
B)Fibromyalsis
C)Fibromyalgia
D)Fibrilomyalsia

Accepted Answer

Fibromyalgia is the correct spelling for a painful muscle condition without weaknesses. The other options are misspelled or do not exist as medical terms.

Question 18

Which of the following root words means 'gray'?
A)Sarc/o
B)Poli/o
C)Pyr/o
D)Lei/o

Accepted Answer

The root word Poli/o means gray, as seen in words like poliosis (graying of the hair) and polioencephalitis (gray matter inflammation in the brain).

Question 19

Myoglobin is a ______________.
A)Carbohydrate
B)Storage protein
C)Acetylcholine
D)Electrolyte

Accepted Answer

Myoglobin is a storage protein found in muscle cells that binds and releases oxygen for energy production during muscle contraction. It is not a carbohydrate, electrolyte or neurotransmitter like acetylcholine.

Question 20

Circular muscle groups are important to ________.
A)Sphincters
B)Extension
C)Rotation
D)Flexion

Accepted Answer

Circular muscle groups are important to sphincters, which are ring-like muscles that control the opening and closing of various passageways in the body, such as the anus and the entrance to the stomach.
