Bone 1

Question 1

What kind of tissue works together in a bone?

Answer 1

Bone or osseous, cartilage, dense connective tissues, epithelium, adipose and nervous.

Question 2

What type of tissue is bone tissue?

Answer 2

Living

Question 3

What happens in the remodelling process?

Answer 3

Old bone tissue gets broken down and new bone tissue gets built.

Question 4

What constitutes the skeletal system?

Answer 4

The entire framework of bones and their cartilages.

Question 5

What are the six basic functions the skeletal system performs?

Answer 5

Support, Protection, Assistance in movement, Mineral homeostasis, Blood cell production and Triglyceride storage (chemical energy storage).

Question 6

How does the skeleton support the body?

Answer 6

By providing a framework, by supporting soft tissues and providing attachment points for the tendons of most skeletal muscles

Question 7

How does the skeletal system protect the body with example?

Answer 7

The skeleton protects most internal organs from injury, just as the cranial bones protect the brain

Question 8

How does the skeleton system assist in movement?

Answer 8

As the skeletal muscles attach to bones, when the muscles contract they pull on the bones. So together the muscles and bones produce movement.

Question 9

How do the bones go about mineral homeostasis?

Answer 9

Bone tissue stores many minerals mainly calcium and phosphorus. On demand bones can release minerals into the blood to maintain critical mineral balances (homeostasis) and to distribute the minerals to other parts of the body.

Question 10

How do the bones make blood cells?

Answer 10

Within specific bones is connective tissue called red bone marrow which produces red blood cells, white blood cells and platelets which is a process named hemopoiesis.

Question 11

How does triglyceride storage in the bone play a part in chemical energy stores?

Answer 11

Triglycerides stored in the adipose cells of yellow bone marrow are an important chemical energy reserve.

Question 12

What is the mechanism muscles allow the body to move through?

Answer 12

Locomotion

Question 13

What is an endoskeleton?

Answer 13

An internal skeleton made up of living tissues which grow at the same rate as the organism

Question 14

What is a vertebrate w examples?

Answer 14

A vertebrate is an animal with a backbone/spine and an internal skeleton, such as mammals, fish and reptiles

Question 15

What is an invertebrate with examples?

Answer 15

An invertebrate is an animal without a backbone such as worms, jelly fish and crabs.

Question 16

What two parts does the mammalian skeleton consist of?

Answer 16

The axial skeleton and the appendicular skeleton.

Question 17

What is the axial skeleton?

Answer 17

The axial skeleton consists of bones in the centre of the body such as the skull, backbone and ribs. -80 bones

Question 18

What is the appendicular skeleton?

Answer 18

The appendicular skeleton is made up of the upper and lower limbs plus the bones forming the girdles which connect the limbs to the axial skeleton.

Question 19

Name the basic bones of the axial skeleton-

Answer 19

The zygomatic bone (cheek bone), the frontal bone (forehead), the parietal bone (behind forehead above ears to mid-back head), the occipital bone (bone below the parietal at the base of the skull), the nasal bone, the temporal bones (temple bones), the maxilla (upper jaw) and the mandible (lower jaw), the sternum, the ribs, the vertebral column and the sacrum (at bottom of the vertebral column)

Question 20

Name the basic bones of the appendicular skeleton-

Answer 20

The clavicle (collar bone), the scapula (the shoulder blade), the humerus, the radius, the ulna, the carpals (the 8 bones of the wrist), the metacarpals (the 5 bones of the hand between the phalanges and carpals) the phalanges (the 14 bones found in the fingers of each hand), the pelvic girdle (hip bone), the femur (top of leg), the patella (knee cap), the tibia, the fibula, the tarsals (seven regular shaped bones around the ankle area of foot), the metatarsals (the five long bones found in each foot) and the phalanges (the 14 bones that make up the toes on each foot).

Question 21

Why are bones so hard?

Answer 21

As they contain calcium salts and if they didn’t contain calcium they would become very soft and rubbery
