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.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
