Bone Landmarks

Lab Objectives: Learn how to identify the bone marking of the skeleton that can be felt on the bodies surface.  In this lab you are going to identify a series of bone markings on another human being by examining their external anatomy.  If you don’t have a classmate in your area, invite a family member or friend to be your model. Exercise 46 (8th edition: pages 493-512; 9th edition pages:675-689 lab manual) may be a helpful reference.



Assignment Instructions: This lab contains 7 activities for you to complete. I have made a Bone Marking worksheet that will help you record the location of the bone markings as you go along.  Write up a paragraph and post to a dropbox on the course site that identifies the location of each bone marking using correct anatomical terminology (inferior/superior, lateral/medial, anterior/posterior) combined with any tricks you can think of to remember where the marking is located (e.g, iliac crests:  superior, anterior, lateral surface of each illium bone; this is where I put my hands when I want my kids to clean up their toys). You are welcome to submit photographs to support your written description but pictures are not required.   When you have completed the entire lab take the post lab quiz on the course site. This quiz is set to be taken as many times as you like and randomize the questions each time. Your highest score will go into the gradebook-so use this to study if you find it helpful.



Activity 1: Face

Watch the short video on the frontal bone articulations. I think it does a good job of introducing some of the harder facial bones. After you watch the video, find the bone markings listed below on your model.

Identify the following on your model:

  1. Angle of the mandible
  2. Zygomatic arch
  3. Ramus of mandible
  4. Mastoid process



Activity 2: Vertebral Column

Find the bone markings listed below on your model.

  1. Spinous process



Activity 3: Boney Thorax

Watch the short video on the how the ribs articulate with the vertebrae. Afterwards find the bone markings listed below on your model.

Identify the following on your model:

  1. 2nd rib
  2. Count your remaining ribs
  3. Manubrium
  4. Xiphoid process of sternum
  5. Sternal angle of sternum



Activity 4: Shoulder (also check out Axilla, Posterior Shoulder and Arm)

There are two short videos on the shoulder to watch. They do a great job of identifying the important parts of the shoulder through external palpation.   After you watch the videos, find the bone markings listed below on your model.  There is also an extra credit opportunity with this Activity:  Find an model willing to wear a white tee shirt. After you watch the videos, label the important components of the shoulder on the white tee shirt as the instructor in the video is doing. Post pictures of the anterior and posterior view of the shirt (please do not include your model’s face) to the LabNoteBook Lab 6 with a short commentary on how easy/hard and useful/or not this activity was for the 5 extra credit points.

Identify the following on your model:

  1. Clavicle
  2. Spine of scapula
  3. Acromion of scapula
  4. Medial border of scapula
  5. Inferior angle of scapula



Activity 5: Arms (see videos: Boney Landmarks of the Upper Limbs; Forearm; Axilla, Posterior Shoulder and Arm)

Watch the short video on the elbow joint. Afterwards find the bone markings listed below on your model.

Identify the following on your model:

  1. Greater tubercle of the humerus
  2. Lateral and medial epicondyls of the humerus
  3. Olecranon process of ulna
  4. Head of the radius
  5. Styloid processes of radius and ulna
  6. Head of the ulna



Activity 6: Pelvis

Watch the short videos on the pelvis. Afterwards, find the bone markings listed below on your model (also check out: Hip and Posterior Thigh and Leg) video.

Identify the following on your model:

  1. Iliac crest
  2. Anterior superior iliac spine
  3. Ischial tuberosity



Activity 7: Legs: (see videos: Anterior and Medial Thigh; Leg and Foot; Hip and Posterior Thigh and Leg)

There are two short videos on the thigh/legs. They do a great job of identifying the important parts of the lower limbs and the second one uses external palpation.   After you watch the videos, find the bone markings listed below on your model. 

Identify the following on your model:
  1. Greater trochanter of femur
  2. Patella
  3. Tibial tuberosity
  4. Tibia: Lateral / medial condyles
  5. Head of the fibula
  6. Tibial tuberosity
  7. Medial maleolus
  8. Lateral malleolus
