1

Components of the axial skeleton

Cranium, vertebrae, hyoid, sternum and ribs

2

Components of the appendicular skeleton

Pectoral girdle, pelvic girdle, humerus, radius, ulna, carpus, metacarpals, femur, phlanges, patella, tibia, fibula and metatarsals

3

Where would you find compact bone tissue

The outer layer of all bones

4

What type of bone is found on the inside of bones

Spongey or cancellous bone

5

What is contained within cancellous bone

Trabeculae

6

What are trabeculae

Lamellae that are arranged as rods or plates

7

What is found between the trabeculae

Red bone marrow

8

Different classes of bones

Long bone, short bone, flat bone, irregular bone and sesamoid

9

Characteristic of long bones

Their height is greater than their width

10

Characteristic of a short bone

Usually pretty compact, their height and width are usually the same

11

Example of a long bone

Humorous, phalanges and metacarpals

12

Example of a short bone

The bones found in the wrist and ankle

13

Characteristic of flat bones

They are thin sheets of bone

14

Example of a flat bone

The side of the skull and the scapula

15

Characteristic of an irregular bone

They dont have any... they're irregular

16

Example of an irregular bone

The vertebrae

17

Characteristic of a sesamoid bone

They are embedded in a tendon

18

Example of a sesamoid

The patella and the bone underneath the metatarsal (tarsal bone)

19

Three classifications of joints

Fibrous, cartilaginous and synovial

20

Describe fibrous joints

Made up of fibrous material that connects the bones, exhibit little or no movement and have no joint cavity

21

Describe cartilaginous joints

Made up of cartilage between the bones, they exhibit little or no movement and have no joint cavity

22

Six sub classifications of synovial joints

Plane (gliding), condyloid, saddle, hinge, pivot and ball and socket

23

Functions of muscles

Movement of the skeleton and organs, posture and body support and heat production

24

The three muscle types are

Smooth muscle, cardiac muscle and skeletal muscle

25

Example of smooth muscle

The intestines

26

Example of cardiac muscle

The heart

27

Example of skeletal muscle

The biceps

28

Three categories of muscles are

Fusiform, broad sheet and pennate

29

Description of fusiform muscles

Tendon on each side with a belly of muscle in the middle

30

Description of broad sheet muscles

Have flat sheet of tendon running along the length of them with muscle fibres coming off of one side
