Question 6

Which of the following best describes the function of the intervertebral disc, and what is the most common site for herniation?

Question 9

During a lumbar puncture, at which vertebral level is the needle typically inserted, and why is this location chosen?

Accepted Answer

Question 10

Which of the following best explains the clinical significance of spina bifida occulta?

Accepted Answer

Question 11

Which structures of the rib articulate with the body and transverse process of the vertebrae, respectively?

Accepted Answer

Head with the body; tubercle with the transverse process

Question 12

Where are the intercostal vessels and nerves located, and what is the clinical significance of this during procedures such as thoracentesis?

Accepted Answer

Just inferior to each rib, so procedures should be performed at the upper border of the rib below to avoid injury

Which hormone is primarily responsible for the growth of the ductal system in the breast, and which structure does it influence?

Accepted Answer

Estrogen; ductal system

Question 14

A patient presents with a rapidly expanding chest wound and severe respiratory distress. Air is entering the pleural cavity but cannot escape, causing a mediastinal shift. What is the diagnosis, and what is the immediate treatment?
