Growth Plate
Area where bones grow in a length until a person reaches maturity then stop growing
4 of 45
Bone Minerals
Bones take up minerals from diet to make them strong and hard so they are able to withstand impact.

Medullary Cavity
Hollow space down middle of compact bone that contains bone marrow

Projection of bone that is used for muscle or tendon attachment
8 of 45
What is a border?
This is the edge of the bone

Saddle joint
Only found in thumbs, allows joint to move in 3 planes, backwards, forwards and side to side and across. Gives us manual dexterity e.g being able to hold a cup
10 of 45
Articular cartilage
Bluish-white covering of cartilage which prevents wear and tear on bones
11 of 45
Ligaments
Hold two or more bones making up the joint in place

Chordae Tendineae
Known as the heart strings, are cord-like tendons that connect the papillary muscles to the tricuspid valve and the bicuspid valve in the hear
13 of 45
Coronary Arteries
Artery supplying blood to the heart.
14 of 45
Vasoconstriction
the constriction of blood vessels, which increases blood pressure.
15 of 45
Vasodilation
the dilatation of blood vessels, which decreases blood pressure
16 of 45
Platelets
a small colourless disc-shaped cell fragment without a nucleus, found in large numbers in blood and involved in clotting
17 of 45
Nasal Cavity
Warm, moisturize, and filter air entering the body before it reaches the lungs.
18 of 45
Epiglottis
Seal off the windpipe during eating
19 of 45
Pharynx
Filter, warm, and moisten air and conduct it into the lungs
20 of 45
Larynx
Houses the vocal folds, and manipulates pitch and volume
21 of 45
Trachea
Provides air flow to and from the lungs for respiration. Connects the larynx to the bronchi
22 of 45
Bronchus
Shuttle air to and from the lungs
23 of 45
Bronchioles
Passageways by which air passes through the nose or mouth to the alveoli (air sacs) of the lungs
24 of 45
Lungs
Enable breathing - Oxygen enters our lungs as part of the air that we breathe. It goes to the blood vessels deep in our lungs and then on to all parts of our body.
25 of 45
Alveoli
tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream.
26 of 45
Diaphragm
separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity and performs an important function in respiration: as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.
27 of 45
Thoriac Cavity
the second largest hollow space of the body. It is enclosed by the ribs, the vertebral column, and the sternum, or breastbone, and is separated from the abdominal cavity
28 of 45
Pleura
Aids optimal functioning of the lungs during breathing.
29 of 45
Intercostal Muscles
The external intercostal muscles are responsible for forced and quiet inhalation. ntercostal muscles are responsible for forced exhalation
30 of 45
Cardiac Muscle
It is an involuntary, striated muscle that is found in the walls of the heart.
31 of 45
Skeletal Muscle
It is a form of striated muscle tissue which is under the voluntary control of the somatic nervous system
32 of 45
Epimysium
Sheath of fibrous elastic tissue surrounding a muscle.
33 of 45
Perimysium
The sheath of connective tissue surrounding a bundle of muscle fibres.
34 of 45
Endomysium
Meaning within the muscle, is a wispy layer of areolar connective tissue that ensheaths each individual myocyte (muscle fiber, or muscle cell).
35 of 45
Fascicle
Bundle of structures, such as nerve or muscle fibres or conducting vessels in plants
36 of 45
Nerve Impulse
A signal transmitted along a nerve fibre. It consists of a wave of electrical depolarization that reverses the potential difference across the nerve cell membranes.
37 of 45
Action Potential
Change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell.
38 of 45
Neuromuscular Junction
Chemical synapse formed by the contact between a motor neuron and a muscle fiber. ble to transmit a signal to the muscle fiber, causing muscle contraction.
39 of 45
Neurotransmitter
Chemical substance which is released at the end of a nerve fibre by the arrival of a nerve impulse and, by diffusing across the synapse or junction,
40 of 45
Synergist
A substance, organ, or other agent that participates in an effect of synergy.
41 of 45
Fixator
A muscle that serves as a stabilizer of one part of the body during movement of another part.
42 of 45
Preparation
Action or process of preparing or being prepared for use or consideration
43 of 45
Execution
Carrying out of a plan, order, or course of action.
44 of 45
Follow Through
Continuation of the movement of a bat, racket, or club after striking a ball
