An ankle sprain is a common injury that involves the stretching or tearing of one or more tendons.

False - ligaments, not tendons

The ____________ vertebrae serve as a link between the thoracic spine-rib cage and the head.

cervical

C2 cervical vertebrae is unique due to presence of

dens.

Triceps surae refers to the

gastrocnemius and soleus

The gluteus medius muscle is located _________ and performs ________ of the hip joint.

medially; abduction

The ___________ process can be palpated on the posterior surface of the spine when it is flexed.

spinous.

The nerve root for the ulnar nerve is:

C8, T1

Each toe has three interphalangeal joints except for the great toe which has only two.

False

The cuboid bone is located medially with respect to the navicular bone.

False

A substantial number of low back problems are caused by improper use of the back over time.

True

Dorsiflexion is the dorsal aspect of the foot moving toward the anterior tibia.

True

Each thoracic vertebrae has one pair of ribs that attaches to it laterally.

True

Functions of the acetabular femoral joint include weight bearing and locomotion.

True

Muscles that are considered to be wrist flexors include the flexor carpi radials, flexor carpi ulnaris, and palmaris longus.

True

Normally, the hip joint can be abducted to approximately 35 degrees.

True

The body will gradually, over time, attempt to adapt very specifically to the various stresses and overloads to which it is subjected

True

The femoral nerve innervates essentially all of the hip flexor muscles.

True

The iliofemoral or Y ligament is located posteriorly and prevents hyperextension.

True

The most palpable point of the femur at the hip is the greater trochanter.

True

The names of individual phases of sports skills may vary depending upon body part involved.

True

The normal curves of the cervical and lumbar spines are lordotic.

True

The obturator nerve innervates both the adductor longus and gracilis muscles.

True

The patella is classified as an "irregular" bone.

True

The patella serves as a pulley by improving the angle of pull with the result being a greater mechanical advantage for the quadriceps during knee extension.

True

True

The tibia bears the majority of the weight as compared to the fibula.

True

The tibial tuberosity serves as the insertion point for all of the quadriceps muscles.

True

Ulnar flexion is movement of little finger side of hand toward medial aspect or ulnar side of forearm.

True

Vertebrae increase in size from the cervical to the lumbar region because the lower back supports more weight.
