Hyaline Cartilage
No, fibrocartilage is not the only type used in creating the embryonic skeleton. The embryonic skeleton primarily consists of hyaline cartilage, which serves as a precursor to bone in endochondral ossification. Fibrocartilage may play a role in specific areas, such as intervertebral discs, but it is not the main component of the embryonic skeleton.

Cartilage forms the embryonic skeleton before being replaced by bone. Additionally, cartilage at joints provides a smooth surface for movement and helps absorb shock. In the trachea, cartilage rings provide structure and prevent collapse during breathing.
A porpoise does indeed have an internal skeleton inside of them. The porpoise skeleton is anywhere from 4.6 to 6.2 feet in length and consist of rib bones, a backbone and upper vertebrea.
The larynx, coastal cartilages, and embryonic skeleton are all formed from cartilage. Cartilage is a firm, flexible connective tissue that provides structure and support to these specific areas of the body during development and growth. Once fully developed, some cartilage may ossify (turn into bone) while other cartilage structures persist in their cartilaginous form.
The skeleton is divided into two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton consists of the skull, vertebral column, and rib cage, providing support and protection for the brain, spinal cord, and thoracic organs. The appendicular skeleton includes the bones of the limbs and the pelvic and shoulder girdles, facilitating movement and interaction with the environment. Together, these components form a framework that supports the body and enables various physical activities.
The embryonic skeleton is primarily formed by a cartilage model, specifically hyaline cartilage, which later ossifies to become bone through the process of endochondral ossification. This cartilage framework provides the initial shape and structure for the future bones. At joints, the surfaces of bones are covered by articular cartilage, also composed of hyaline cartilage, which facilitates smooth movement and reduces friction between bones during articulation.
The appendicular divison (126 bones) consist of the pectoral girdle, upper limbs, pelvic girdle, and lower limbs.
No, the axial skeleton consists of bones along the central axis of the body, including the skull, vertebrae, and ribcage. The appendicular skeleton consists of bones of the upper and lower limbs, as well as the shoulder and pelvic girdles.
