AK Anatomy & Physiology Fundamentals 3

Question 1

In AK, the psoas muscle weakness is most commonly associated with dysfunction in which organ system?

Accepted Answer

Kidneys and adrenal glands

Answer

In the AK organ-muscle relationship framework, the psoas major is associated with the kidneys and adrenal glands.

Question 2

The anterior longitudinal ligament of the spine primarily resists which motion?

Accepted Answer

Extension

Answer

The anterior longitudinal ligament runs along the anterior vertebral bodies and limits hyperextension of the spine.

Question 3

Which type of muscle fiber contracts slowly, is highly resistant to fatigue, and is predominant in postural muscles?

Accepted Answer

Type I (slow oxidative)

Answer

Type I (slow-twitch) fibers have high oxidative capacity and mitochondrial density, making them ideal for sustained postural activity.

Question 4

A patient presents with weakness of hip abduction. Which muscle is most likely primarily inhibited?

Accepted Answer

Gluteus medius

Answer

The gluteus medius is the primary hip abductor and its inhibition is a common clinical finding in AK assessment of pelvic dysfunction.

Question 5

The thoracolumbar fascia plays a critical role in force transfer during lifting because it connects:

Accepted Answer

The erector spinae to the gluteus maximus via the posterior layer

Answer

The posterior layer of the thoracolumbar fascia allows force transfer between the erector spinae, gluteus maximus, and latissimus dorsi during functional movements.
