Lab Anatomy Notes: Bones, Calvarium, Cadaver Samples, and Exam Strategy

Guaranteed questions will come from the first slide of the lab material, with two possible options to choose from.
The top of the skull is called the calvarium; removing it reveals the bones inside the skull.
When the calvarium is removed, the interior bones are the same bones as the exterior; there is no double layer of bones.
The instructor indicated there are multiple points of emphasis (six identified features to study), and likely about half of them will appear on the quiz (roughly 2–3 of the 6).
Time management and prep: students should study the PowerPoint last slide closely to assist with identifying bone features and names on the quiz.

The calvarium is the upper domelike portion of the skull that can be removed to expose interior bone anatomy.
After removing the calvarium with a bone saw, the inner bones visible are the same bones that form the exterior skull.
Important reminder: there is no extra layer of bones inside; exterior and interior bones are the same bones in the skull.
On the quiz, you will be tested on:
- Names of bones (bone identities)
- Bone features (landmarks, processes, features on bones)
- A few microscope-related questions
- Cadaver bone samples provided for identification and comparison
Bone features tend to be more challenging than simple bone name recall and are highlighted as the major difficulty on the lab exam.

Cadaver bone specimen on the table:
- Includes a long bone (illustrative of the femur) with a section available for study under a dissecting microscope.
- Approximately $3-4$ cadaver bone sections will be available for reference during study time.
Microscope slides:
- A bone slide will be chosen at random for testing; students may try to focus and observe.
- The PowerPoint slide set contains the slides that will be useful for the microscope questions.
PowerPoint last slide:
- The last slide contains images and descriptors to help identify bone pictures when selecting the correct terms on the quiz.
No skull image or skull-related item will appear on this quiz (no skull questions).

Most points will come from:
- Names of bones (e.g., identifying which bone is pictured or described)
- Bone features (landmarks, processes, surfaces)
A portion of points will come from:
- Microscope questions based on the slides
- Cadaver bone observations and comparisons
The features on the lab exam are the primary challenge; the naming of bones is also important but features tend to be more demanding.
You should expect the following distribution:
- About $2-3$ questions on the six identified features/names from the first slide (roughly $frac{1}{3} - frac{1}{2}$ of the six items)
- A few microscope questions (≈ $3$ ) and a few cadaver bone questions (≈ $3-4$ )
Quiz day logistics:
- Time window before quiz: approximately $1.5$ hours from now for study, followed by the quiz itself.
- Clipboards with answer sheets and scantron sheets will be provided.
- You will not be tested on skull anatomy for this quiz; focus on names, features, and slide-based questions.

Immediate study goal: study the PowerPoint thoroughly to recognize pictures and match them with the correct terms.
Suggested study block: around $1$ hour of solid, focused study on the PowerPoint content and cadaver bone references.
After initial study, the instructor will circulate to help with:
- Distinguishing right vs. left sides (which will not appear on the quiz but may be useful for practice)
- Identifying challenging bones such as the carpals and the bone features.
Exam day plan:
- Prepare to take the quiz after the allotted study period.
- Be ready to indicate you need help by raising your hand (the instructor’s cue: “put the arm up” meaning you need assistance, not injection).
- Remember: there will be no skull component on this quiz; focus on the remaining topics.

Bone names vs bone features:
- Names of bones covered in the module
- Key bone features on those bones (landmarks, processes, surfaces)
- Relationships between bone shapes and their functions
Carpal bones and other challenging bones:
- Carpals are highlighted as particularly tricky; expect targeted practice on identifying them.
Microscopy:
- Ability to identify key histological features on bone slides (as presented on the PowerPoint slides)
Cadaver bones:
- Recognize and compare the long bone (femur) section and other cadaver bone specimens on the table
- Use the cadaver bone slides as a reference for the microscopic and morphological features

Practical implications:
- Training with cadaver bones provides real-world context for bone morphology and anatomy.
- Microscope practice helps connect microscopic features with macroscopic anatomy.
- Understanding the difference between names and features helps reduce confusion during the quiz.
Test-taking strategy:
- Prioritize bone features over color/shape guesses since features are the major challenge.
- Use the PowerPoint last slide as a quick-reference cheat sheet during practice.
- Be comfortable with identifying bones from pictures and matching them with terms.
- Practice right vs left orientation to build confidence, even if it won’t be directly used on the quiz.

Contents to study: $6$ items (bone features/names) with a likelihood of $2-3$ appearing on the quiz; about $frac{1}{3} - frac{1}{2}$ of the items will be tested.
Cadaver bone references: approximately $3-4$ samples on the table to study.
Cadaver bone long bone example: the long bone of the thigh (femur) is pictured as part of the cadaver section.
Study window before quiz: about $1.5$ hours from the start time for the session, followed by the quiz.
Perfection goal for this quiz: aim to be a $11/10$ or a $10/10$ score (i.e., exceptionally high performance; note that the instructor contrasts this with the second quiz, where scores near perfection are unlikely).

Do not expect skull questions on this quiz; focus on names, bone features, and microscope content.
The last slide of the PowerPoint is a key resource for picture-to-term identification.
Be ready to identify and name bones and their features using the provided PowerPoint and cadaver bone references.
If you need help during the study period, raise your hand to get assistance from the instructor.
