3.03b Skeletal system Reading check

Last updated 6 months ago
15 questions
You can begin preparing for our Medical Terminology midterm and final by joining my class Quizlet group. This optional but a great study resource.
You can view a spreadsheet with all of the terms here.
In this unit we'll be learning about the Anatomy & Physiology of the Skeletal system.

We'll focus on three learning targets in this assignment:
  1. Describe the structure and function of bones
  2. Identify the different types of bones
  3. Differentiate between the axial and appendicular skeleton

Here is a link to the recording from today's lesson.

Past recording links:
Here is a recording from our class session last school year.

Here are the lesson slides for this unit - we only covered the first section today but feel free to look ahead at our next two lessons.
3.01 Functions of a Skeleton
2

Which of the following are functions of the skeletal system?
(select all of the choices that are correct)

2

How might a forensic science technician use knowledge of the skeletal system in their everyday work?

2

Match the two types of bone formation processes with their description

Draggable itemCorresponding Item
Calcification
The process of building an embryo’s bones.
Ossification
the development of bone from the time an individual is born, and it continues throughout their entire life.
2

Match the 4 types of bone cells with their description.

Draggable itemCorresponding Item
Osteogenic cells
The only bones cells that divide. They divide into osteoblasts.
Osteoclasts
The cells that generate new bone by creating osteocytes and other proteins that build the strong bone matrix.
Osteoblasts
Mature bone cells that lie within the fully formed bone and are located in the lacuna, a small chamber in the calcified matrix of the bone.
Osteocytes
Cells are responsible for the maintenance and repair of bone
3.02 Types of Bones and Bone Tissue
1

Match the descriptions of the two types of bone with their characteristics.

Draggable itemCorresponding Item
Cancellous (spongy) bone
Does not have osteons. Found on the ends of long bones. Has internal branches called trabeculae.
Compact bone
Has many cylinder shaped units called osteons. Makes up the smooth tissue on the outside of bone.
1

What substance is located in the medullary cavity of a long bone?

3
Other Answer Choices:
Medullary cavity
Epiphysis
Metaphysis
Diaphysis
Compact bone
Spongy bone
3

Match the five types of bones with their description.

Draggable itemCorresponding Item
Long bones
Built to withstand a great deal of weight and provide support. Are found in the arms and legs.
Flat bones
Mostly spongy and cube shaped. Allow for movement.
Irregular bones
Provide protection for soft tissues like the brain and lungs.
Sesamoid bones
Surrounded by tendon and their shape resembles a sesame seed.
Short bones
Shapes that don't fit into a particular category.
4

Move the stages of healing from a bone fracture in order from the time of fracture (first) unti healing (last).

  1. Hemotoma
  2. Soft callus
  3. Hard callus
  4. Remodeling
3.03 Names and Locations of Bones
1

Bone projections are features that stick out and bone depressions are holes or indentations in bone.

1

Which of the following is true about a Crest bone projections.

1

What type of bone depression is a cavity or hollow space within a bone?

2

Select the bones from the list below that are part of the Appendicular Skeleton.

There are 4 correct choices

On which side of the knee joint is the ACL located?

1

What questions do you have about the skeletal system?

I will do my best to answer your questions during our next class session or I can also reply to you here.
