Which muscle group is primarily responsible for lumbar spine extension?
Answer: Erector spinae
The erector spinae group (iliocostalis, longissimus, and spinalis) are the primary extensors of the lumbar spine.
What is the term for the angle between two body segments at a joint when a movement decreases that angle?
Answer: Flexion
Flexion is defined as a movement that decreases the angle between two body segments at a joint.
Which ligament prevents anterior displacement of the femur on the tibia?
Answer: Anterior cruciate ligament
The anterior cruciate ligament (ACL) prevents the femur from sliding anteriorly and limits excessive knee extension.
Which rotator cuff muscle internally rotates the shoulder?
Answer: Subscapularis
The subscapularis is the only rotator cuff muscle that performs internal (medial) rotation of the shoulder.
A client cannot raise onto their toes on one foot. Which nerve is most likely involved?
Answer: Tibial nerve
The tibial nerve innervates the gastrocnemius and soleus, which are responsible for plantarflexion needed to rise on toes.
The term 'valgus' refers to a joint angulation in which the distal segment is deviated:
Answer: Laterally away from the midline
Valgus describes lateral deviation of the distal segment, as seen in knee valgus (knock-knees) where the knees angle inward.
Which of the following best describes concentric muscle contraction?
Answer: The muscle shortens while producing force
Concentric contraction occurs when a muscle shortens as it produces force, overcoming external resistance.
