Study Notes

Cranial Bones and Features

Lacrimal bone is not part of the cranium.
The sagittal suture is found between the two parietal bones.
The frontal bone is an unpaired cranial bone.
The sphenoid bone spans the width of the cranial floor and forms the base of the skull.
The nasal bone does not contain a sinus.

Sphenoid Bone

The sphenoid bone is located at the floor of the skull.
Sella turcica is the region of the sphenoid bone in contact with the pituitary gland.
Lesser wings of the sphenoid bone contain the optic canal.
Olfactory foramina are not a landmark of the sphenoid bone.
The sella turcica is best described as a depression.
The sphenoid bone contains a sinus.

Vertebral Structure

The centrum is another name for the body of a vertebra.
The spinous process is the vertebral projection oriented in the median plane.
Inferior articular processes articulate immediately with the vertebra below.
Intervertebral discs are not found within a vertebral foramen.
Transverse processes are lateral projections of a vertebra.
Lamina is most accessible from a posterior surgical approach.

Cervical Vertebrae

The first cervical vertebra is called the atlas.
The second cervical vertebra is known as the axis.
The articulation site between the occipital bone and atlas allows nodding "yes".
The articulation between atlas and axis permits head rotation, shaking "no".
The occipital condyles of the skull articulate with the atlas.
The atlas lacks both a body and a spinous process.

Scapula Anatomy

The spine is found on the posterior surface of the scapula.
The glenoid fossa is the socket for the shoulder joint.
The acromion process articulates with the clavicle.
The subscapular fossa is located on the anterior surface of the scapula.
Suprascapular notch is found on the superior border of the scapula.
The coracoid process does not articulate with another bone.

Hip Bone Structure

The adult hip bone consists of three regions: ilium, ischium, and pubis.
The auricular surface of the ilium articulates with the sacrum.
The ischial tuberosity is the landmark felt when sitting.
The indentation inferior and lateral to the auricular surface is known as the greater sciatic notch.
The ilium is the largest region of the hip bone.
The acetabulum is the articulation site for the femur.
The obturator foramen is a large hole in the hip bone.

Femur Anatomy

The iliac crest is the ridge-like superior edge of the ilium.
The hip bone articulates with the sacral region of the vertebral column.
The pubic tubercles can be palpated on the anterior surface near the midline.
The posterior inferior iliac spines are not the hip bone projections felt on the hips.
The ischial spine projects from the greater sciatic notch.

Tibia and Fibula

The patellar surface is a landmark found on the anterior surface of the femur.
The head of the femur forms part of the hip joint.
The femur is particularly susceptible to fractures at the neck.
The trochanter is a unique landmark of the femur.
The linea aspera is found on the diaphysis of the femur.
The head of the femur is positioned medial and proximal to the body.

Ankle and Foot

The superior surfaces of the medial and lateral condyles of the tibia articulate with the femur.
The fibula is the bone located lateral to the tibia.
The medial malleolus is a noticeable bump on the medial surface of the ankle.
The femur articulates with the proximal end of the tibia.
The tibial tuberosity is found on the anterior surface of the tibia.

Miscellaneous

Surgical removal of the mastoid process may lead to impaired head and neck movements.
Fetal vertebrae develop through endochondral ossification from a hyaline cartilage model.
A cleft palate arises from the failure of the right and left maxillae bones to fuse during fetal development.
Isch- refers to the hip joint, while supra- means above or higher.
Inter- indicates between or among, and meta- suggests after or behind.
