Flashcards in A&P 3.5 blood pressure & vascular disorders Deck (28):
1

carpals

8 bones

scaphoid, lunate, triquetrum, pisiform
trapezium, trapezoid, capitate, hamate

some lovers try positions that they can't handle

2

Phalanges named

Proximal, middle, distal

Each bone has a
Base
Shaft
Head

3

Extensor digitorum

O,I, A

Origin: LATERAL epicondyle of the humerus

Insertion: proximal, middle (intermediate) and distal phalanges of four fingers (NOT THE THUMB)

Action: extension of the fingers at the interphalangeal joints and the metacarpalophalangeal joints

4

Gracillis

A, I, O

Origin: inferior RAMUS of the pubis

Insertion: anterior proximal, medial tibia ( pes anserinus)

Action: adduction of the lower extremity, flexion of the knee

5

Pectinious is

Most anterior and most superior of the adductors

6

Magnus is

GRACILIS is

Magnus is deepest

GRACILIS is most medial

7

Functions of blood vessels

Transportation of essential materials to/from cells which happens at the capillary level (microcirculation)
Entire mechanism of circulation is to keep capillaries supplied with blood for the cells

8

Function of arteries

Distribute blood to arterioles which provide resistance and with smooth muscle cause vasodilation and vasoconstriction which assists blood flow

9

Function of veins

Collectors and reservoirs that not only return blood to the heart, but can hold varying amounts of blood without change in blood pressure because of their ability to stretch, called capacitance. Veins often called capacitance vessels

10

Capacitance

Veins ability to hold varying amounts of blood without change in blood pressure due their ability to stretch

11

Arteries of the head and neck

Left and right carotid

12

Arteries of the extremities and trunks

Upper: left and right subclavian arteries

Trunk: thoracic and abdominal aorta

Lower: left and right iliac arteries (from abdominal aorta)

13

General principles about veins

They increase in size going back to the heart
Presence or absence of veins is variable and they often have similar names and locations as arteries
Superior vena cava collects blood from the upper extremities/head with EXCEPTION OF THE LUNGS

14

Systemic veins

Veins of the head and neck: left and right jugular veins
Veins if upper extremity: left and right subclavian veins
Veins of the thorax: superior vena cava
Veins of the lower extremity: left and right sapphenous veins

15

Hepatic portal circulation

Blood goes specifically to an area before return to the heart, blood collected from the GI to liver for filtration of nutrients. Then from liver to inferior vena cava to the heart.

16

Blood pressure measured with a

Sphygmomanometer
Measures the amount of air pressure equal to the BP in an artery in terms of mm Of mercury
Sounds are call KOROTKOFF sounds

17

Arterial BP

Parts and normal reading

Systole/diastole - normal 120/80

18

Systolic BP

The force of blood pushing against arterial walls during ventricular contraction

19

Diastolic BP

The force of blood when ventricles are relaxed

20

Blood pressure

The difference between systolic and diastolic BP

It is increased in arteriosclerosis and aortic valve insufficiency

21

Arterial and Veinus bleeding

Blood exerts a much higher pressure in arteries then veins.
Arteries - gush
Veins - seep

22

Vascular disorders

Aneurysm
Atherosclerosis
Hypertension
Raynaud's syndrome
Cerebrovascular accident (CVA)
Shock

23

Aneurysm

Section of artery or vein that is abnormally widened because of a weakening of the wall

Contraindicated

24

Atherosclerosis

Inelastic brittle arteries due to plaques of lipids that calcify.

Many risk factors

MASSAGE WITH CAUTION - NONE ON ADVANCED

25

Hypertension

High blood pressure

WITH CAUTION - DOCTOR NOTE

26

Raynaud's syndrome

Episodes of vasospasm of arterioles usually in fingers and toes
Attacks can last for minutes or hours
IS INDICATED

27

Cerebrovascular accident

Brain aneurysm/stroke
From ischemia of brain tissue caused by embolism

CONTRAINDICATED

28

Shock

Failure of the circulatory system to deliver oxygen to tissues

COUNTERINDICATED
