muscular skeletal system

Question 1

musculoskeletal system

Answer 1

musculoskeletal system: consists of the skeletal system (bones and joints) and the skeletal muscle system (voluntary or striated muscle). Working together, these two systems protect the internal organs, maintain posture, produce blood cells, store minerals and enable the body to move.

Question 2

skeletal system

Answer 2

skeletal system: consists of the bones and joints

Question 3

skeletal muscle system

Answer 3

skeletal muscle system: voluntary or striated muscle

Question 4

muscular system

Answer 4

The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body

Question 5

skeleton

Answer 5

skeleton: the bones or shell of an animal that support and protect it as well as allowing movement

Question 6

bones

Answer 6

bones: the pieces of hard tissue that make up the skeleton of a vertebrate

Question 7

bone marrow

Answer 7

bone marrow: a substance inside bones in which blood cells are made

Question 8

Cartilage

Answer 8

cartilage: a waxy, whitish, flexible substance that lines or connects bone joints or, in some animals such as sharks, replaces bone as the supporting skeletal tissue. The ears and tips of noses of people are shaped by cartilage.

Question 9

calcium

Answer 9

calcium: an element occurring in limestone, chalk, also present in vertebrates and other animals as a component of bone, shell etc. It is necessary for nerve conduction, heartbeat, muscle contraction and many other physiological functions.

Question 10

phosphorus

Answer 10

phosphorus: a substance that plays an important role in almost every chemical reaction in the body. Together with calcium, it is required by the body to maintain healthy bones and teeth.

Question 11

minerals

Answer 11

minerals: any of the inorganic elements that are essential to the functioning of the human body and are obtained from foods

Question 12

ossification

Answer 12

ossification: hardening of bones

Question 13

brittle

Answer 13

brittle: breaks easily into many pieces

Question 14

joint

Answer 14

joint: a region where two bones meet

Question 15

ligaments

Answer 15

ligaments: a band of tough tissue that connects the ends of bones or keeps an organ in place

Question 16

synovial fluid

Answer 16

synovial fluid: the liquid inside the cavity surrounding a joint that helps bones to slide freely over each other

Question 17

pivot joint

Answer 17

pivot joint: the joint that allows a twisting movement

Question 18

hinge joints

Answer 18

hinge joints: joints in which two bones are connected so that movement occurs in one plane only

Question 19

ball and socket joints

Answer 19

ball and socket joints: joints where the rounded end of one bone fits into the hollow end of another

Question 20

imovable joints

Answer 20

immovable joints: joints that allow no movement except when absorbing a hard blow

Question 21

muscles

Answer 21

muscles: tissue consisting of cells that can shorten

Question 22

involuntary muscles

Answer 22

involuntary muscles: muscles not under the control of the will; they contract slowly and rhythmically. These muscles are at work in the heart, intestines and lungs.

Question 23

voluntary muscles

Answer 23

voluntary muscles: muscle attached to bones; it moves the bones by contracting and is controlled by an animal’s thoughts

Question 24

tendons

Answer 24

tendons: tough rope-like tissue connecting a muscle to a bone

Question 25

greenstick fracture

Answer 25

greenstick fracture: a break that is not completely through the bone, often seen in children

Question 26

fracture

Answer 26

fracture: a break in a bone

Question 27

stem cells

Answer 27

stem cells: undeveloped cells found in blood and bone marrow

Question 28

osteoporosis

Answer 28

osteoporosis: loss of bone mass that causes bones to become lighter, more fragile and easily broken

Question 29

sprains

Answer 29

sprains: injury caused by tearing a ligament

Question 30

arthritis

Answer 30

arthritis: a condition in which inflammation of the joints causes them to swell and become painful

Question 31

tennis elbow

Answer 31

tennis elbow: an injury due to strain or overuse that causes the elbow’s lining to become inflamed and painful

Question 32

torn hamstrings

Answer 32

torn hamstrings: a common sporting injury caused by overstretching the hamstring muscle, which joins the pelvis to the knee joint
