MBLEx Flashcards

Kinesiology

The MBLEx Kinesiology content area assesses the exam candidate’s understanding of structures and systems of the body responsible for movement. Massage exam applicants should have a strong foundation in muscle location, origin and insertion points, action, and relative position. MBLEx candidates must also understand the components of the muscular, nervous and skeletal systems of the body, and how they work together to produce movement. Flashcards are an important tool for any massage student to include in their MBLEx test prep plan. 

Components and characteristics of muscle

Myofibrils are basic units of a muscle cell, and are composed of what two proteins?
actin and myosin
This section of striated muscle is located between two Z lines:
sarcomere
The rectus femoris is an example of what muscle shape or fiber direction?
bipennate
What are 3 types of muscle in the human body?

What is the dense fibrous connective tissue that encloses muscles and merges with the tendons?
fascia
What is the cell membrane of striated muscle fiber cells called?
sarcolemma

Concepts of muscle contraction

What is the source of energy for muscle contraction?
ATP (adenosine triphosphate)
Muscle contraction that occurs without changing muscle length is called:
isometric contraction
What is the mechanism of muscle contraction that is based on muscle proteins moving past each other?
sliding filament theory
A muscle or muscle group that opposes the force of another muscle group is called:
antagonist
During what type of muscle contraction does the muscle shorten as it contracts?
concentric contraction
Smooth muscle of the GI system contracts in a wavelike rhythm called ________ .
peristalsis

Proprioceptors

What receptors in skeletal muscle detect changes in muscle length and contribute to proprioception?
muscle spindles
What kind of activities can strengthen proprioception?
balance exercises; strengthening exercises; exercising with eyes closed
Tendons and joint capsules contain receptors called _______ that can sense changes in muscle tension.
Golgi tendon organ (GTO)

Muscle origin, insertion, action...

What is the insertion point of the upper trapezius?
lateral clavicle and acromion
What is the origin of the pronator teres?
medial epicondyle of humerus, coronoid process of ulna and common flexor tendon
What two muscles protract the scapula?
pectoralis minor aan serratus anterior
What nerve passes through the superficial and deep portions of the supinator?
radial nerve
What muscle stabilizes the pelvis when standing on one foot?
gluteus medius
The flexor carpi radialis performs what two actions at the wrist?
flexion and adduction (radial deviation)
The pectinous is part of which muscle group?
hip adductors
Which muscle of the hamstring group also originates at the posterior aspect of the femur?
biceps femoris
What are the layers of abdominal muscles, from superficial to deep?
Rectus abdominis, external obliques, internal obliques, transversus abdominis
What muscle of the posterior leg crosses both the knee and ankle joints?
gastrocnemius
What is the origin of the Teres Major?
inferior angle of the scapula (dorsal surface)
What muscle originates at the proximal 2/3 of anterior shaft of fibula, and functions to dorsiflex the ankle and extend the 4 lateral toes?
extensor digitorum longus

Joint structure and function

What type of joint is capable of the greatest mobility?
synovial (also called diarthrodial)
The glenohumeral joint is formed by what two structures?
the head of the humerus and the glenoid fossa of the scapula
What is the large weight-bearing joint formed where the spine meets the pelvis?
sacroiliac joint
What kind of joint is the tibiofemoral joint?
modified hinge joint (it can rotate when the knee is flexed)
What are the bands of dense regular connective tissue that connect bone to bone?
ligaments
What is the tough outer layer that surrounds a synovial joint?
joint capsule (or articular capsule)
What smooth rubbery tissue covers the ends of long bones to protect the bone and reduce friction?
cartilage
Fibrous joints that permit very little or no movement, such as those in the skull, are called _________ .
synarthrosis
What is an example of a saddle joint in the body?
the 1st carpometacarpal joint (thumb)

Range of motion

What tool is used to measure range of motion?
goniometer
What is the best position to assess hip flexion ROM?
supine
What is the normal ROM of the knee?
0 - 140 degrees
How would you document knee ROM measurement if the client has 110 deg. flexion and is 10 deg. away from full extension?
-10 - 110 deg.
What term is used to describe the resistance that a therapist senses when assessing the limits of a client's ROM?
end feel
What type of ROM can be performed without touching the client?
active range of motion
