Anatomy & Kinesiology Flashcards

Which plane of the body divides it into left and right halves?

Answer: Sagittal plane

The sagittal plane divides the body into left and right portions; the midsagittal plane passes exactly through the midline.

The radial pulse is assessed at which anatomical location?

Answer: Lateral side of the wrist over the radius

The radial artery runs along the lateral (thumb-side) aspect of the wrist, making it the standard site for pulse assessment.

Which term describes the anatomical position where a person stands upright with palms facing forward?

Answer: Anatomical position

Anatomical position is the standard reference posture: standing erect, feet shoulder-width apart, arms at sides, palms facing anteriorly.

Hyperextension of the wrist during an escort hold can damage which structure on the anterior forearm?

Answer: Flexor tendons and median nerve

Forced wrist hyperextension overstretches the flexor tendons and can compress or stretch the median nerve, causing pain, numbness, or injury.

Which of the following best describes the function of the rotator cuff muscles?

Answer: They stabilize the glenohumeral (shoulder) joint during movement

The four rotator cuff muscles (SITS) hold the humeral head in the glenoid fossa, stabilizing the shoulder joint through its wide range of motion.

The peroneal (fibular) nerve wraps around which bony landmark and is at risk during lower-extremity restraint holds?

Answer: Head of the fibula

The common peroneal nerve curves around the fibular head just below the lateral knee; direct pressure there can cause foot drop and lateral leg numbness.

What does the term 'distal' mean in anatomical directional language?

Answer: Further from the point of origin or attachment

Distal means farther from the point of attachment or the body's center; the fingers are distal to the elbow.
