Random
100
A place where the elements of skeleton come together.
Joints
100
This is the functional unit of a muscle fiber.
Sarcomeres, made of myosin (thick filaments) and actin (thin filaments)
100
The amount of blood ejected from the left side of the heart in one minute.
Cardiac Output
100

The inability of muscle to maintain its strength of contraction of tension; may be related to insufficient oxygen, depletion of glycogen, and/or lactic acid buildup.

What is muscle fatigue?

100
This feature in veins helps move blood back to the heart.
Valves. Arteries don't have valves.
200
An instrument for measuring angles (as of joint or skull)
Goniometer
200
Interaction between these two filaments are responsible for muscle contraction.
Myosin and Actin
200
The volume of blood pumped by a ventricle in one heart beat.
Stroke volume
200

A measurement of the electrical activity in a muscle

What is an EMG (electromyogram)?

200
Peripheral artery disease can be diagnosed using this.

Ankle-brachial index (ABI). It compares the blood pressure in your ankle with the blood pressure in your arm. Uses Ultrasound machine.

300
 A usually translucent somewhat elastic tissue that composes most of the skeleton of vertebrate embryos, except for a small number of structures.
Cartilage
300
This type of muscle is dense, contains intercalated discs, and is striated.
Cardiac muscle
300
A condition in which veins become weak, and twisty. Valve do not seem to work and causes fluid accumulation.
Varicose Veins
300

A highly branched polymer of glucose containing thousands of subunits; functions as a compact store of glucose molecules in liver and muscle fibers.

What is glycogen?

300

Ca2+ ions bind to this regulatory protein

What is troponin?

400
An unbending movement around a joint in a limb (as the knee or elbow) that increases the angle between the bones of the limb at the joint.
Extension
400
The attachment of a muscle tendon to a movable bone or the end opposite the origin.
Insertion
400

This artery carries blood to the brain, face, and head.

What are the carotid arteries?

400

Elite sprinters and marathon runners differ in the relative proportions of these types of muscle fibers

What is slow-twitch and fast-twitch?
400

The parasympathetic nervous system is involved in this overall systemic response.

What is "Rest and Digest"?

500
Ball-and-Socket, Pivot, Hinge are all example of this category of joint
Synovial Joints
500
The hardening of the muscle and stiffening of the body that begins 3 to 4 hours after death. Explain why this occurs.
Ca++ moves into the sarcomere with passive transport. To leave, they need ATP for active transport. When you die, ATP is no longer available, so Calcium stays attached to the troponin: Rigor Mortis.
500
Artery walls are composed of layers of epithelial, connective, and this type of tissue.

Smooth muscle

500

These are the first two materials used for energy in muscle contraction.

What are stored ATP and creatine phosphate?

500

These are the three main system that maintain a supply of ATP during exercise, depending on the duration and intensity of the activity.

What is ATP/Creatine (Phosphagen System), Anaerobic (Glycogen-Lactic Acid System), and Aerobic Respiration? Phosphagen System uses creatine phosphate to make energy; for maximum effort and short duration (sprint). Glycogen-Lactic Acid System uses anaerobic espiration to turn glycogen into glucose and ATP; for slower but longer lasting (swimming). Aerobic Respiration uses all remaining glucose, then burns fat reserves, then breaks down proteins; slow but extremely long lasting (marathon).
