Answer 1

The plane which divides ur body into L/R / CUTS STRAIGHT DOWN THE MIDDLE .

Question 2

What’s the transverse plane ?

2

Answer 2

Cuts the body separates top and bottom = superior ( top) and inferior ( bottom)

Question 3

Answer 8

Anterior/ventral- front

Posterior/dorsal- back

Question 9

Superficial ?
Deep?
(2)

Answer 9

Superficial - on the top ( epidermis)

Deep- Dermis is deep to the epidermis ( just means deeper) 😂

Distal ?
(2)

Answer 10

Proximal - in close proximity

Distal - larger distance Away

Question 11

MOVEMENT
what is flexion?
What is extension?
(2)

Answer 11

Flexion—> decreases angle between muscles

Extension—> increases angle between muscle

Answer 12

ABduction- AWAY from the midline

ADDuction-TOWARDS midline

Question 13

What’s lateral and medial rotation ?(2)

Answer 13

Medial rotation-internal rotation towards urself

Lateral rotation - external rotation towards the outside

What’s circumduction? (2)

Answer 14

Adding all the movements up ( circles with ur arms )

2

Answer 15

Supination - rotate ur hands palms up

Pronation- rotate ur hands palms facing dorsally

Question 16

2

Answer 16

• consists of Cranial Cavity and Vertebral spinal cavity

Question 17

What’s does the ventral cavity contain ?

2

Answer 17

• thoracic cavity

- abdominopelvic cavity

Question 18

What does the thoracic cavity contain ?
(Divided into——)
(3 spaces called ———)
(6)

Answer 18

1) subdivided into:
- 2 pulmonary cavities (around the lungs)
- mediastinum (contains the pericardium = sac around the heart)

2) 3 potential spaces called :
- 2 pleural spaces (around the lung)=pleura
- pericardial space a around the heart =pericardium !

Question 19

What separates the thoracic cavity from the abdominopelvic cavity ?
(1)

Answer 19

Diaphragm

Question 20

What’s in the abdominal cavity ?

6

Answer 20

• stomach
• intestines
• spleen
• liver
• gall bladder
• kidneys

Question 21

What’s in the pelvic cavity ?

3

Answer 21

• distal end of large intestine
• urinary bladder
• reproductive organs

Question 22

What are the uses of serous lining membrane (mesothelium) ?

2

Answer 22

• prevents friction hence things don’t get inflamed

- allows movement of lungs and heart

Question 23

What’s happens in between the visceral and partial layers of the mesothelium ?
(1)

Answer 23

-small volume of lubricating fluid (serous fluid)spread widely to prevent friction

Question 24

Where are the 3 MESOTHELIUMS ?

3

Answer 24

1) pleura around lungs
2) pericardium around heart
3) peritoneum around abdominal organs (digestive system)

Question 25

What is the : 1)visceral layer of the mesothelium ? 2)parietal layer of the mesothelium ? (2)

Answer 25

1) visceral layer is near the organ | 2) parietal is near the wall ( opposite side )

Question 26

What does : 1) articulation mean? 2) what’s the origin and insertion point of muscles? What’s the difference ? (3)

Answer 26

1) articulation : area with a joint/bone = 2 bones come together 2) origin = attachment points of muscle more proximal to the Midline of the body Insertion= attachment points of muscles distal from origin

Question 27

What’s a ligament ? What’s tendon ? (2)

Answer 27

1) ligament=band of short connective tissue connects BONE to BONE 2) Tendon= attaches MUSCLE to BONE

Question 28

What’s Anastomosis ? What’s plexus ? (2)

Answer 28

- anastomosis = connection between vessels and nerves (cross-connection between adjacent channels, tubes, fibres, or other parts of a network) -Plexus = branched nerve network : a network of nerves or vessels in the body.

Question 29

What is Aponeurosis ? (2) What’s a bursa ? (2)

Answer 29

Aponeurosis -a sheet of pearly white fibrous tissue that takes the place of a tendon in flat muscles having a wide area of attachment. Bursa-small filled sac that acts as a cushion and gliding surface to reduce friction between tissues of the body.

Question 30

What’s a collateral ? (2) What’s a Raphe? (2)

Answer 30

- backup /extra extension = not the main connective accessory - Raphe - A seem that joins 2 sheets of muscle !
