Document Summary

Osteology of the lower limb: pelvic girdle, femur, tibia, fibula, bones of foot. The segments of the lower limb are the thigh, leg, and foot. Flexion of the hip lift up thigh. Extension of the hip move leg back. Flexion of the leg (knee) bend leg back at knee (bring foot towards back). Extension of the leg (knee) extend leg at knee. There can also be lateral and medial rotation of the hip. Dorsiflexion move foot up (heel on ground). Plantar flexion move foot down (toes on ground). Inversion foot in, lateral side of foot touching the ground. Eversion foot out, medial side of foot touching the ground. The pelvic girdle is similar to the pectoral girdle, but it is a true girdle. The pelvic girdle consists of the paired hip bones. A hip bone is also called an os coxae. Each hip bone meets with the other anteriorly and with sacrum posteriorly.

Type answers please-Thank you!

Sagittal Plane

1. Name the axis that sagittal plane motions occur around Frontal

2. Name the motion that occurs when the forearm moves:

Â· Anteriorly in the sagittal plane Flexion

Â· Posteriorly in the sagittal plane Extension

3. Name the Muscles that causes each of those motions:

Transverse Plane

1. Name the axis that transverse plane motions occur around ______________________

2. Assume the starting position with the elbow joint at 90 degrees of flexion with thumbs pointed to the ceiling, Name the motion that occurs when:

Â· The palm of the hand turns towards the floor _______________________

Â· The palm of the hand turns to the ceiling _______________________

3. Name the Muscles that causes each of those motions:

Kinematically analyze the muscles working at the elbow when performing volleyball serve, include if the muscle is an agonist, antagonist, or stabilizer, and what type of contraction is occurring.

If an athlete injured the medial collateral ligament what muscles would be important to strengthen, why?

In response to the previous question, name (3) exercises someone could perform to strengthen these muscles.

Reverse Case Study

An athlete comes to you stating they have âgolfers elbowâ. What is golfers elbow? What structures are involved?

What presentation do you think you would see for the manual muscle tests and ROM we learned?

1. What in the configuration of the anteriorcompartment makes this region particularly liable to an increase inintracompartmentalpressure?

How would you test forinvolvement of the deep peroneal nerve, keeping in mind thatdorsiflexion of foot and toes may be severely interfered with byanoxia (lack of oxygen) of the muscles in the compartment, and thatloss of muscle action therefore does not necessarily imply nerveinvolvement?

What area of the skinwould you test for sensory loss?

The presence of arterialpulse in the anterior tibial and dorsalis pedis arteries seems toprove patency of the main stem, although, occasionally, awell-established collateral circulation in the lower part of theleg by means of branches from the arteries in the posteriorcompartment may simulate patency in a vessel blocked higherup.

What vessel in theposterior compartment would particularly contribute to suchcollateral circulation?
