Question

What bone in the cow is the T-bone? Is it part of the spine, pelvis or what?

Answer 1

Hint: T-bone can be located from the cow body from a short piece of loin (piece of beef) from the back of the cow body. It has two bones running perpendicular to each other roughly at 90°. Therefore, it is referred to as the T-bone.

Complete answer:
T-bone is present in the spinal processes of the cow. It is one of the lumbar vertebrae having two adjacent bones attached perpendicularly to a transverse spinal bone such that they form a T-shaped structure which is the reason for it being called so. It is a beef section cut from the ventral part of the cow body with sections of beef attached on both the sides of the vertebrae. Such a beef column has comparatively lesser traces of tenderloin. As T-bone is a part of the vertebral column only, it contributes to the formation and functioning of vertebrae.
The body of a cow has a full-fledged system of spinal cord with a combination of small vertebrae bones. There are six lumbar vertebrae. These vertebral bones, when cut in small columns, form a T-shaped structure with flesh attached on both the sides. This bone is actually called a T-bone.
Pelvis is a region lying in between the rectum and urinary bladder. It is a part of the uterus. This region has an opening in vagina which forms the outlet way for the body. Such anatomy is common to most of the female mammals. Hip bones combine with the lower vertebral bones (sacral) to form the pelvic bone frame. T-bone cannot be a part of the pelvis as it is a column of lumbar vertebrae and pelvis includes sacral vertebrae.

Note:
Lumbar and sacral are the names assigned to the vertebral bones. There are a total 50 vertebral bones in the body of a cow, out of which six are lumbar and five are sacral bones. The spine of the cow runs through the vertebral bones.
