Homeostasis

Front 1

Diabetes

Back 1

Problem with homeostasis of the insulin

Front 2

Type I

Back 2

Immune system kills cells in the pancreas that make insulin.

Front 3

Type II

Back 3

The cells in your body do not react to Insulin

Front 4

What is Blood Pressure?

Back 4

The pressure exerted by the blood against the walls of blood vessels.

Front 5

______ Pressure over _______ Pressure.

Back 5

Systolic over Diastolic

Front 6

Process of Measuring Blood Pressure

Back 6

Cutting circulation from left ventricle to hand through the Bracheil Artery

Front 7

Blood pressure depends on the ....

Back 7

Blood pressure depends on the strength of the heartbeat, thickness and volume of the blood, the elasticity of the artery walls, and general health.

Front 8

Sugar Homeostasis

Back 8

The regulation of sugar concentration in the blood and the hormones involved

Front 9

The target organ for Insulin, the ____ which removes______ from the blood by turning it into ________.

Back 9

the liver which removes glucose from the blood by turning it into glycogen.

Front 10

Insulin

Back 10

- Made in Pancreas
- Hormone
- Tells liver to store glycogen
- released when blood sugar rises

Front 11

Glucagon

Back 11

-Hormone
- Tells liver to release glycogen
-released when blood sugar is low

Front 12

Best to take blood pressure on left arm because...

Back 12

The left ventricle is the strongest. The first sound is the spurt of blood from the contraction of the heart and the second is the heart relaxing and the blood flowing

Front 13

Ligament

Back 13

tough, flexible bands of connective tissue holding bones together at joints

Front 14

Tendons

Back 14

tough, inflexible bands of connective tissue attaching muscle to bone

Front 15

Types of Muscle

Back 15

Cardiac,Smooth, and Skeletal

Front 16

Cardiac

Back 16

involuntary muscle of the heart wall.

Front 17

Smooth

Back 17

Involuntary muscle of the stomach, intestines, and blood vessels

Front 18

Skeletal

Back 18

Voluntary, Striated muscel attached to bones

Front 19

Origin

Back 19

Point of attachment on the stationary bone

Front 20

Insertion

Back 20

Point of attachment of the moving bone

Front 21

Action Potentials

Back 21

a self regenerating wave of electrochemical activity

Front 22

Motor Cortex

Back 22

A part of the brain involved in controlling and executing voluntary motor functions.

Front 23

Step 1

Back 23

The brain sends action potentials down axons to the neuromuscular junction (a synapse)

Front 24

Neuromuscular Junction

Back 24

The point at which the axon from the brain reaches the muscle cell - type of synapse

Front 25

Acetylcholine

Back 25

nuerotransmitter - crosses the neuromuscular junction in order to communicate with the muscle cell

Front 26

Step 2

Back 26

nuerotransmitter crosses the neuromuscular junction in order to communicate with the muscle cell

Front 27

Step 3

Back 27

When acetylcholine is seen by the muscle cell, the cell releases calcium into the cytoplasm

Front 28

Muscle Contraction

Back 28

regulated by the level of calcium concentration in the cytoplasm which increases when signals arrive from the brain

Front 29

Actin and Myosin

Back 29

Proteins the make up a muscle cell

Front 30

Step 4

Back 30

When muscle contraction is triggered, myosic forms a chemical bond with actin.

Front 31

Cross Bridge

Back 31

the chemical bond of myosin and actin

Front 32

Step 4

Back 32

the myosin pulls the entire muscle structure together

Front 33

Power Stroke

Back 33

An action requiring ATP where Myosin pulls inward

Front 34

Step 5

Back 34

Myosin releases actin, ending the contraction

Front 35

Flexors

Back 35

the muscels involded in flexion (act of bending a joint)(biceps)

Front 36

Extendors

Back 36

involved in extension of muscle (triceps)

Front 37

Collagen

Back 37

main components of bone (elasticity)

Front 38

Marrow

Back 38

a flexible tissue found in hollow interior of bone

Front 39

Red marrow

Back 39

produces red/white blood cells and plateles, composed of myeloid tissue

Front 40

Yellow Marrow

Back 40

stores and is composed of fat cells

Front 41

Denaturing

Back 41

loose shape with heat – during a high fever the temperature is too high for enzymes to work properly

Front 42

Positive FeedBack

Back 42

In response to a stimulis, (high blood sugar)a positive feedback mechanism will make more substance (insulin)
