Which of the following pairs is correctly matched? A) lumbar vertebrae; bifid spinous processes B) thoracic vertebrae; triangular vertebral foramen C) lumbar vertebrae; short, flat spinous processes D) thoracic vertebrae; transverse foramen E) cervical vertebrae; rib facets

C) lumbar vertebrae; short, flat spinous processes

Explanation:

The Lumbar Vertebrae are bigger and stronger than vertebral bodies in certain positions.

The vertebral bodies and disks bares majority of the body weight of the body. The lamina, facets and spinous process are basic components of the posterior materials that assist in guiding the movement of the vertebrae and as a coverage or protective shelter for the spinal cord.

The spinous process are SHORT and STURDY (FLAT) in the Lumbar Vertebrae. Hence, this explain why it is often referred to as "Hatchet-Shaped".

The attached image as red dots meant to point to the spinous process in the Lumbar Vertebrae.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
