Skeletal System

Question 1

Axial Skeleton

Answer 1

All the bones that do not correspond to any appendages; Skull, Vertebral column, and Thoratic cage

Question 2

Appendicular Skeleton

Answer 2

All the bone inside of the appendages; Humerus, Radius, Ulna, Carpals, Metacarpals, Phalanges and more

Question 3

What are long bones and the three main parts/there functions

Answer 3

Bones that are longer then they are wide;

Epiphyses: Ends of the long bone

Metaphyses: The small space between the epiphyses and the diaphysis

Diaphysis: The shaft of the bone

Question 4

Answer 6

Bone appears flat

Question 7

What are sesamoid bones

Answer 7

Bone is embedded inside tendons

Question 8

What is spongy bones function

Answer 8

Allows bones to withstand extreme pressure without fracturing

Question 9

What is the function of the epiphyseal plate/line and where is it

Answer 9

Inside the metaphyses is a line of cartilage where growth in the bone takes place during childhood

Question 10

Where is the medullary cavity and its function

Answer 10

Inside of the diaphysis; As a adult its yellow marrow(fat)/ As a child its red marrow where erethrocytes formation takes place

Answer 15

Between bones that articulae on the epiphyses;
Thick dense cartilage that absorbs shock and prevents friction

Question 16

Coronal: Runs along the coronal plane connecting the frontal and parietall bones

Squamous: Runs on the Sagittal plane connecting the parietal and temporal bones

Lambdoid: runs on the Dorsal side of the skull connecting the occipital and parietal bones

Question 21

Saddle joints

Answer 27

Joint in the thumb

Question 28

Ellipsoid/Condyloid joints

Answer 28

Condyle fits into the elliptical cavityon another bone, not as deep as the ball and socket
