1.Name the bone that contains the following feature:
Crista galli Ethmoid bone
Mastoid process Temporal bone
Sella turcica Sphenoid bone
Supraorbital foramen Frontal bone
Zygomatic process Temporal bone
2.Which of the bones that form the orbit are cranial bones?
Which are facial bones?
Cranial frontal bone, sphenoid bone, ethmoid bone
Facial lacrimal bones, palatine bones, zygomatic bones,
maxilla bones
3.Which four bones articulate with the LEFT parietal bone?
Name the sutures that join these bones to the left of the parietal
bone.
Right parietal bone via the sagittal suture
Frontal bone via the coronal suture
Left temporal lobe via the squamous suture
Occipital bone via the lambdoid suture
4.Professor Ron Singer pointed to the foramen magnum of the
skull and said, “That is where the food goes. The food passes
down through this hole when you swallow.” Some of the
students believed him, but others said this was a big mistake.
Can you correct his statement?
The foramen magnum is where the spinal cord passes through.
5.Dave has a tumor on his pituitary gland that requires surgery.
The operation will require exceptional surgical skill both to
reach the gland and to avoid serious, possibly fatal,
complications. A) Discuss the location of the pituitary gland and
the associated anatomical features that make such an operation
so delicate. B) Where is the safest location in the cranium where
the surgeon can enter to remove the tumor?
A)The pituitary gland is located on the sella turcica of the
sphenoid bone. Associated anatomical features that make the
operation delicate:
- the cavernous sinuses that contain carotid arteries
- being near the brain can cause damage to nearby brain tissue
can cause stroke, or blindness, and it can cause meningitis from
infection
B)The safest location to enter is through the sphenoid sinus.
6.Straight neck syndrome or otherwise known as military neck,
occurs when the curvature of the cervical spine becomes
straight. The number of patients diagnosed with this syndrome
has greatly increased in recent years. Why might this be? Think
about the normal curvature of the spine. What are some
symptoms?
The most common cause of military neck is poor posture, which
can result from staring at the computer or mobile devices,
occupational conditions , or repetitive movements. This is most
likely why the number of cases has increased in recent years.
Some symptoms are stiffness, decreased range of motion,
headaches, pain in the neck and the extremities, muscle
weakness, and spine deformity.
7.Which bones are present in the joint that allows you to shake
your head “YES” and which ones are present in the joint that
allows you to shake your head “NO”? Explain which bone
features allow this to occur.
YES: The atlas and the occipital bone form the atlanto-
occipital joint.
NO: The atlas and axis form the atlanto-axial joint
8.Allison is a 30-year old woman who has been healthy all of
her life. She recently became pregnant and as the size of her
baby grows, so does the pain in her lower back. What area is
being affected, why is it being affected, and what is this called?
Hormone increase causes the joints and ligaments to soften to
prepare the body for delivery later on, known as hyperlordosis.
9.What specific features of the thoracic vertebrae articulate with
the head of a rib? Where does the tubercle of a rib articulate?
The head of the rib articulates with the costal facets located on
the bodies of thoracic vertebrae and the rib tubercle articulates
with the facet located on the vertebral transverse process.
10.Which bone/bone features does the superior articular facet of
a vertebra articulate with?
It articulates with an occipital condyle on the underside skull
11.Match bones in column B to descriptions in column A. (some might be repeated).
