Briefly describe the five categories of bones found in the human body based on the shape of the bones.
The human body contains five types of bones based on shape long bones have greater length and width and consist of the shaft in a variable number of extremities short bones are somewhat cube shaped because they’re nearly equal in length and width flap loans are generally fan and composed of two nearly parallel plates of compact bone tissue enclosing a layer of spongy bone tissue irregular bones have complex shapes and cannot be grouped into any of the previous categories sesamoid quoins develop in certain tendons where there is considerable friction tension and physical stress and I shaped-similarly to a sesame seed

Briefly describe the bones that make up the orbit include a description of the portion of the orbit formed by each bone
Parts of the frontal and sphenoid bones comprise the roof of the orbit. Parts of the zygomatic and sphenoid bones form the lateral wall of the orbit. Parts of the maxilla, zygomatic and palatine bones makeup the floor of the orbit. Parts of the maxilla, lacrimal, and ethmoid and sphenoid bones form the medial wall of the orbit.
Briefly describe the functions of the fontanels
The fontanelles are important in allowing flexibility during childbirth and a little brain and girls after birth.
Briefly describe the function of the paranasal sinuses
The sinuses lighten the skull and containing mucous membrane lining that helps moisten and clean inspired air in the sign is also aid in Hensing the quality of the voice by acting as resonating chamber

There are seven cervical vertebrae in the neck region. There are 12 thoracic vertebrae posterior to the thoracic cavity. The five lumbar vertebrae support the lower back. There is one sacrum consisting of five used sacral vertebrae. There is one coccyx tailbone consisting four fused coccygeal vertebrae.
Ribs that have coastal cartilage that attaches directly to the sternum are called
True ribs
The turbercle found on the neck of a rib articulates with the facet found on the
Transverse process of a thoracic vertebra
