Human Osteology I – Axial Skeleton
Objectives:
After the lab, you should be able to:
Identify the major bones of the human body by name, location, and shape.
Describe the different types of human teeth and how they function.
Identify the anatomical planes of the body.
Correctly orient the body in standard anatomical position.
Locate the major muscles of mastication.
Describe the types of motion that occur at joints between bones.
To become familiar with the methods biological and forensic anthropologists use to identify
an individual's sex by looking at skeletal remains (skull and pelvic girdle).
Station 1. The Skull
Instructions: Examine the skull at this station noting that the skull is made up of many bones
joined by sutures.
1.
Which bones make up the cranial vault (bones surrounding the brain)?
Frontal, Parietal, Temporal, Occipital, Sphenoid, and the Ethmoid
2.
Which bones make up the face?
Mandible, Maxilla, Frontal bone, Nasal bones, and Zygoma
3.
For each of the following bones, identify whether the bone is paired or singular:
Maxilla
Paired
Zygomatic
Paired
Mandible
Singular
Frontal
Singular
Parietal
Paired
Temporal
Paired
Occipital
Singular
Sphenoid
Singular
4.
Name the bones that articulate (come together) at each of the following sutures.
1
Coronal
Frontal and Parietal
Sagittal
Parietal
Temporal
Occipital, Parietal, and Ethmoid
Lambdoidal
Parietal and Occipital
5.
Locate the foramen magnum.
5a. On what bone is the
foramen magnum located?
Occipital
5b. What soft-tissue feature
passes through the foramen
magnum?
The spinal cord
6.
Which two bones make up the zygomatic arch?
Temporalis and Zygomatic
7.
The temporalis muscle, a muscle of mastication, originates from the cranium and inserts on
the mandible.
7a. List the bones to which the temporalis muscle attaches on the side of the cranium.
The temporalis muscle attaches to the temporal line on the parietal bone and goes under the
zygomatic arch.
7b. What is the name of the raised ridge of bone that demarcates the superior and
posterior limit of the temporalis’ origin?
Temporal line
7c. The temporalis muscle travels beneath the zygomatic arch, through a space called the
temporal foramen. Some species have a large temporal foramen, while other species
have a smaller temporal foramen. What can you infer about the size (and therefore
strength) of the temporalis muscle? Would a larger temporalis be found in species
with softer diets or in species that eat hard/tough items?
If smaller then weaker, and if bigger then stronger. A larger one would be found in species that
eat hard/tough items.
8.
To what bones does the masseter muscle attach?
It attaches to the outside of the zygomatic arch and wraps a little bit under the bottom of
mandible
2
Station 2. The Dentition
1.
Compare and contrast the shape of each of the types of teeth listed below. For example,
count the number of cusps (points) on each tooth type. Does each type have cusps? Does the
number of cusps differ between the maxillary (upper) and mandibular (lower) dentition?
Incisor:
No cusp
Canine:
1 cusp
Premolar
:
2 cusps
Molar:
3-5 cusps
2.
Which bones anchor the teeth?
Alveolar bones
3.
Briefly describe how you use your incisors to acquire and process food.
They are for cutting and chopping food
4.
Briefly describe how you use your premolars and molars to acquire and process food.
They are for mashing, grinding, and breaking up food
5.
A dental formula describes the number and types of teeth found in the maxilla and
mandible. To calculate the dental formula, count up the number of incisors, canines,
premolars, and molars in each half of the maxilla and mandible at write it like this
(#maxillary incisors: # maxillary canines: number of maxillary premolars: number of
maxillary molars/#mandibular incisors: # mandibular canines: number of mandibular
premolars: number of mandibular molars). For example, for a capuchin monkey the dental
formula is 2:1:3:3/2:1:3:3
5a. What is the adult human
dental formula?
2:1:2:3/2:1:2:3
5b. What is the dental formula for
an adult chimpanzee?
2:1:2:3
5c. How do the canines of chimpanzees and gorillas differ from that of a human?
The canines of a gorilla or a chimpanzee are way larger than a human.
5d. What is the dental formula for
this monkey?
2:2:2:3

Types of Fractures
Using the X-RAYS at each station, answer the following questions:
1. A 23-year-old male comes to the ER with a gunshot wound in the distal femoral region. The x-ray reveals
the bone is shattered into multiple pieces. Pieces of lead can be seen in the x-ray. The ER doctor
recommends the patient see orthopedic doctor for surgical repair. What type of fracture is this?
2.
A 24-month-old pediatric patient comes into the clinic. Mom states that the child was running on the
concrete at the park and fell with her arms outstretched. Her frontal region has a hematoma and there is
swelling in the lower arm. X-rays reveal an oblique fracture. What bone is broken?
3. 7-year-old girl comes into the ER with an injury cause from a four-wheeler accident. The patient was a
rider not the driver of the vehicle. Patients states that "brother slung her off" and she tried to catch
herself with an outstretched arm. Mom states that patient's arm was hyperextended at the elbow joint.…

Patient Name:
Patient Age:
Scenario:
You are a physician and your patient has broken a
bone (chose the bone using proper A&P
terminology) located in the
(axil or
appendage) skeletal system. The break is part of
(compact bone and/or the joint
system). The break is a
(transverse fracture, greenstick, comminuted,
oblique, spiral or avulsed). You need to decide
how the break happened, the age of your patient,
and what you will do to heal the bone.
Today:
Research the different types of bone breaks and
pick a type of break. Then create a story of how
the break happened.
The story needs a date, place, time, and what the
person was doing.
Your to assessment is to fill out a doctor's report explaining the nature of the break

You also need to provide an explanation for how the Skeletal System responds to the situation.
1) Anthony has been living in Western WA for 3 years. After moving from California and seeing his health decline, including weight gain, fatigue, joint pain, arthritis, and weakness, he decided to go to the doctor to get checked out. The doctor discovered Anthony has a Vitamin D deficiency (which you should have figured out in module #1). Anthony also has deterioration in his joint cavities, especially the connective tissue on the end of the long bones as well as abnormally porous bone tissue. After an X-ray they also found stress fractures on his tibia.
