Which spinal region is most commonly affected by work-related musculoskeletal disorders in office workers?
Answer: Lumbar
The lumbar spine bears the most compressive load during prolonged sitting, making it the most common site of work-related back pain.
What is the name of the fibrocartilaginous discs located between vertebral bodies?
Answer: Intervertebral discs
Intervertebral discs act as shock absorbers between vertebral bodies and can herniate under excessive compressive or shear forces.
The carpal tunnel is formed by the carpal bones and which ligament?
Answer: Transverse carpal ligament
The transverse carpal ligament (flexor retinaculum) forms the roof of the carpal tunnel through which the median nerve and flexor tendons pass.
Which muscle group is primarily responsible for maintaining upright posture of the spine?
Answer: Erector spinae
The erector spinae muscle group runs along the spine and provides the primary extensor force needed to maintain upright posture.
What term describes the force per unit area applied to a tissue?
Answer: Stress
Mechanical stress is defined as force divided by cross-sectional area and is a key factor in tissue injury thresholds.
Tendons connect which two types of structures?
Answer: Muscle to bone
Tendons are dense connective tissue structures that transmit the contractile force of muscle to bone to produce movement.
