What is a vertebrae in biology?

A vertebra is an irregular bone with some hyaline cartilage component. The typical vertebra has the following parts: a body and a vertebral (neural) arch with several processes (e.g. articular, transverse, spinous). The spinal vertebrae include 7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae.

Where is the vertebrae?

The vertebrae are the bony building blocks of the spine. There are seven cervical vertebrae in the neck, twelve thoracic vertebrae in the upper back, and five lumbar vertebrae in the lower back.

What is the function of the body of a vertebra?

What are the 33 vertebrae?

Vertebral Column and Spinal Cord The vertebral column (VC) is composed of 33 vertebrae [cervical (C), 7; thoracic (T), 5; lumbar (L), 5; sacral (S), 5; coccygeal, 4], which are interconnected by intervertebral (IV) disks (except C1, C2) and stabilized by spinal ligaments.

What is the largest vertebrae?

lumbar vertebrae
The lumbar vertebrae are located between the ribcage and the pelvis and are the largest of the vertebrae. The pedicles are strong, as are the laminae, and the spinous process is thick and broad.

What does T11 and T12 control?

They are called T11 and T12. Your lowest 2 ribs are attached to these vertebrae. The areas of the body and functions of the body controlled by the nerves exiting these vertebrae control: Kidneys, Ureters, Small Intestines, Colon, Uterus, Lymph Circulation, and the Buttocks.
