The thickest portions of the anterior longitudinal ligament and the supraspinous ligament are found in which regions of the vertebral column? A. Cervical B. Lumber C. Sacral D. Thoracic

The anterior longitudinal ligament is thickest in the thoracic region of the vertebral column, while the supraspinous ligament is thickest in the lumbar region.

Option: D & B respectively.

Explanation:

The ligament that stretches down the back of the spine is understood as "longitudinal anterior". This passes through all the vertebral bodies and intervertebral disks. It is thicker and marginally narrower over the vertebral bodies, although thinner but slightly wider over the intervertebral discs, far less prominent than that seen in the longitudinal ligament afterwards.

A powerful fibrous cord that binds the apices of the spinous processes from the seventh cervical vertebra to the sacrum is understood as "supraspinous ligament". The fibrocartilage get generated in the ligament at the sites of fixation to the peaks of the spinous processes.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
