Chapter 7 Axial Skeleton HW

Which vertebra does NOT have a body? A) atlas B) last lumbar C) last cervical D) axis

A) Atlas

Curvatures of the spine serve the body by ________. A) giving additional springiness and flexibility to the spine which absorbs shock B) providing space for soft organs in the various body cavities C) applying greater pressure to the intervertebral disks preventing them from slipping D) limiting the flexibility of the spine and preventing hyperextension

A) Giving additional springiness and flexibility to the spine which absorbs shock

What are the major functions of the intervertebral discs? A) to absorb shock and provide flexibility to the spine B) to remove curvatures of the spine and provide springiness to the spinal column C) to prevent hyperextension and allow rotation of the spine D) to hold together the vertebra and support the body

A) To absorb shock and provide flexibility to the spine

Thoracic vertebrae differ from the other vertebrae in that they have ________. A) no transverse processes B) no intervertebral discs C) costal facets D) transverse foramina

D) Frontal bone

Paranasal sinuses are found in which of these facial bones? A) nasal conchae B) zygomatic bones C) vomer D) maxillae

D) Maxillae

Which part of the ethmoid bone forms the superior part of the nasal septum? A) cribriform plate B) orbital plate C) crista galli D) perpendicular plate

D) Perpendicular Plate

What is the major function of the axial skeleton? A) provide an attachment point for muscles that allow movement B) give the body resilience C) provide a space for the major digestive organs D) provide central support for the body and protect internal organs

D) Provide central support for the body and protect internal organs

The sphenoid bone is sometimes referred to as a "key stone" of the skull. This is due to the fact that ________. A) the sphenoid is wedged in the superior most portion of the skull and supports all of the other bones below (excluding the mandible) B) the sphenoid bone is solid like a stone and provides the strength necessary to support the skull C) the intricate shape of the sphenoid makes it critical to the distinct characteristics of the individual human face D) the sphenoid is in the center of the skull and it articulates (joins) with all of the other bones of the skull (excluding the mandible)

D) The sphenoid is in the center of the skull and it articulates (joins) with all of the other bones of the skull (excluding the mandible)
