Zoology Lesson 5 SS

Question 1

This is the central framework of our body. it consists of bone, cartilages, tendons, ligaments, and joints

Answer 1

Skeletal System

Question 2

How many bones does a regular human have?

Answer 2

206 bones

Question 3

It forms the vertical, central axis of the body and includes all bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs.

Answer 3

Axial Skeleton

Question 4

This includes all bones of the upper and lower limbs, plus the bones of the pectoral and pelvic girdles that attach each limb to the axial skeleton.

Answer 4

Appendicular Skeleton

Question 5

This bone is cylindrical in shape, longer than it is wide. Its function is in movement and support.

Answer 5

Long bone

Question 6

This bone is cube-like in shape, approximately equal in length, width, and thickness. Its function focuses on providing stability and support while allowing some motion.

Answer 6

Short bone

Question 7

This bone is thin and curved. Its function involves providing points of attachment for muscles and protecting internal organs.

Answer 7

Flat Bone

Question 8

This bone has a complex shape and functions to protect internal organs, as well as to facilitate movement and provide support.

Answer 8

Irregular

Question 9

This bone is small and round, embedded in tendons. It protects tendons from excessive forces and allows for effective muscle action.

Answer 9

Sesamoid

Question 10

This is a smooth and flexible substance covering the tips of the bones where they meet.

Answer 10

Cartilage

Question 11

These are bands of tissue that connect the ends of a muscle to your bone.

Answer 11

Tendons

Question 12

These are bands of tissue that attach one bone to another bone.

Answer 12

Ligaments

Question 13

This is also known as an articulation. It is a joint where two or more bones in the body come together.

Answer 13

Joints

Question 14

An immovable or nearly immovable joint is characterized by a strong union between the articulating bones. This immovable nature is crucial at locations where the bones protect internal organs.

Answer 14

Synarthrosis

Question 15

This joint type has limited mobility. An example of this type of joint is the cartilaginous joint that unites the bodies of adjacent vertebrae. Filling the gap between the vertebrae is a thick pad of fibrocartilage called an intervertebral disc.

Answer 15

Amphiarthrosis

Question 16

A freely moveable joint, most commonly found in the appendicular skeleton, is characterized by ____. These joints provide the limbs with a wide range of motion.

Answer 16

Diarthrosis

Question 17

What are the function of Skeletal System?

Answer 17

1. Support, Movement, and Protection
2. Mineral and Fat Storage, Blood Cell Formation

Question 18

This is an age-related disorder in which bones lose mass, weaken, and break more easily than normal bones.

Answer 18

Osteoporosis

Question 19

This is a break in a bone which occurs when it is put under sudden or very strong pressure or force.

Answer 19

Fracture

Question 20

This is an abnormal curvature of the spine resulting in an S or C shape.

Answer 20

Scoliosis

Question 21

This is a joint disease that results from the breakdown of joint cartilage and bone. The most common symptoms are joint pain and stiffness.

Answer 21

Osteoarthritis
