KINE EXAM 3

When considering the elbow forearm, what three bones do we have?

Humerus Radius Ulna

The Osteokinematic design of the spinal column is such that movement is possible in which of the following cardinal plans?

Sagittal

Frontal

Transverse

During thoracolumbar extension, there is more flexibility in the thoracic vertebrae compared to the lumbar vertebrae; therefore more range of motion is performed during thoracolumbar flexion than thoracolumbar extension (T/F)?

True

A patient visits our clinic, and we notice that their elbow rests at ~32 degrees away from their body: What name would we use for this condition? options are:

Normal Cubitus Valgus

Excessive Cubitus Valgus

Normal Cubitus Varus

Excessive Cubitus Varus

Excessive Cubitus Valgus

This specific nerve activates the posterior muscles of the upper arm and descends towards the thumb and index finger of the hand.

Radial Nerve

As it pertains to Activities of Daily Living (ADL), an individual is usually capable of performing elbow flexion and extension within 30-130 degrees ROM (T/F)?

True

TRUE OR FALSE The elbow joint is a modified hinge joint due to the rotation that is presented within the proximal and distal radioulnar articulation

TRUE

The bones that makeup the forearm perform 4 articulations, what are they?

Humero ulnar

Humero radial

Proximal radio ulnar

Distal radio ulnar

When made specific to ADL ( Activities of Daily Living ), what range of motion, in degrees, is found for pronation and supination?

50-50 degrees

What is the largest muscle in the arm by volume?

Brachialis

TRUE OR FALSE. The MC nerve descends the arm innervating the biceps brachi, coracobrachialis, triceps brachi and brachialis.

FALSE

What nerve runs through the anterior muscles in the elbow joint?

(MC) Musculocutaneous Nerve (C5-C7)

What nerve runs through the posterior muscles in the elbow joint (along the radius then thumb)?

Radial Nerve (C5–T1)

What is the purpose of the Median Nerve?

Comes from the C5-T1 column ; motor and sensory movement in the hand

The medial aspect of the trochlea is positioned slightly (_________) to the cubital space when compared to the lateral aspect

Inferior

Which portion of the os coxa makes up the smallest portion of the acetabulum?

Pubis

Bones of the pelvis combine anteriorly at the sacrum and posteriorly at the pubic symphysis to create a basin like structure, known as the "pelvic girdle" but also known as "os coxae." (T/F).

FALSE

How wide is the acetabular notch at rest In terms of degrees ?

55-65 degrees

Of the ligaments within the hip, what is the strongest ? (also the strongest in the human body).

Iliofemoral ligament

The femoral head is positioned ~ 125 degrees within the hip, with a medial direction of the shaft and an anterior curvature on the bone (T/F).

True

Which stance would be placing the hip in a position of ~20 degrees extension?

1. Heel Off

2. Mid stance

3. Initial Heel Contact

4. Heel Contact

Heel off

how many bones are in the cervical region of the spine?

C-7

how many bones are in the Thoracic region of the spine?

T-12

how many bones are in the Lumbar region of the spine?

L-5

how many bones are in the sacral region of the spine?

S-5

how many bones are in the Coccyx region of the spine?

C-4

why do 90% of the annular discs stretch when the spine twists?

because the collagen ring in the annulus fibrosus are tilted 25 degrees; they become elongated during torsion.

On average, with the knee flexed, the hip flexes to 120 degrees, which is reduced to 70 degrees when the knee is extended (why?)

when the knee is extended, the hamstring muscles limit further extension.

what 2 parts of the acetabulum are tied for making up most of the acetabulum

ischium and ilium

Which stance would be placing the hip in a position of ~30 degrees extension?

1. Heel Off

2. Mid stance

3. Initial Heel Contact

4. Heel Contact

initial & heel contact

Which stance would be placing the hip in a position of ~0 degrees extension?

1. Heel Off

2. Mid stance

3. Initial Heel Contact

4. Heel Contact

mid stance

What is the name of the articulating portion of the hip socket?

Lunate surface
