What tissue is the forerunner of long bones in the embryo?
A
elastic connective tissue
B
dense fibrous connective tissue
C
fibrocartilage
D
hyaline cartilage
Explanation: 

Detailed explanation-1: -Endochondral ossification begins with mesenchymal tissue transforming into a cartilage intermediate, which is later replaced by bone and forms the remainder of the axial skeleton and the long bones.

Detailed explanation-2: -Answer and Explanation: Bone formation begins at around week 8 of embryonic development. Prior to osteogenesis, or the creation of bone tissue, the embryonic skeleton is made of hyaline cartilage.

Detailed explanation-3: -Hyaline cartilage tissue (also referred to as hyaline connective tissue or hyaline tissue) is a type of a cartilage tissue. It is the most common type of cartilage characterized by a glossy and smooth appearance. Where is hyaline cartilage found? Hyaline cartilage is found around the bones of free-moving joints.

Detailed explanation-4: -Hyaline cartilage is the most widespread and is the type that makes up the embryonic skeleton. It persists in human adults at the ends of bones in free-moving joints as articular cartilage, at the ends of the ribs, and in the nose, larynx, trachea, and bronchi.

Detailed explanation-5: -Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and an epiphyseal line. The epiphyseal line is a remnant of an area that contained hyaline cartilage that grew during childhood to lengthen the bone.
