21
Q

Describe fibrous joint and its movement.

A

Found between bones or cartilage
Joined by fibrous CT
Has little movement

22
Q

What are the two types of fibrous joint?

A

Sutures and Syndesmoses

23
Q

What are sutures?

A

Fibrous joints formed between flat bones eg. skull

24
Q

What are Syndesmoses?

A

Formed between 2 long bones e.g distal end of tibia and fibula

25
Q

What are 2 types of cartilaginous joints?

A

Primary and Secondary

26
Q

Describe Primary joints.

A

Jointed by hyelin cartilage, has no movement and are found on epiphyseal growth plates

27
Q

Describe secondary joints.

A

Connected by fibrocartillage and are found in the mid-sagittal plane and offer limited movement.

28
Q

Describe synovial joints.

A

Allows movement

Has a smooth bone articulation due to think layer of hyeline cartilage which is lubricated by synovial fluid secreted by synovial membrane

The joint is enclosed in a CT capsule

29
Q

Name the 6 types of synovial joints.

A
Hinge
Condyloid
Ball and Socket
Plane
Pivot
Saddle
30
Q

Movement of hinge?

A

One plane - flexion and extension - example is elbow

31
Q

Movement of Condyloid?

A

2 planes - flexion and extension, abduction and adduction and also circumduction.

Example is wrist

32
Q

Movement of Ball and Socket?

A

3 planes - Flexion/extension, abduction/adduction and rotation.

Example is glenohumeral joint - shoulder joint

33
Q

Movement of plane?

A

Allows a gliding movement

Example is carpal bones

34
Q

Movement of pivot?

A

One bone rotating around the other

Example is the distal/proximal radioulnar joints distal to elbow joint.

35
Q

Movement of saddle?

A

Same as condyloid joints yet saddle shaped

36
Q

Do humans show anatomical variation?

A

Yes, however if extreme its classed as an anatomical anomaly

37
Q

What is embryology?

A

Study of developmental changes in utero

38
Q

What is histology?

A

Study of microscopic images of tissues

39
Q

Use of histology?

A

Allows us to understand how parts of the body are put together physically

40
Q

What are the two main types of bone?

A

Spongy and Compact

41
Q

What is compact bone?

A

Dense bone forming the outside of the bone - protects body and provides support

42
Q

What is spongy bone?

A

Porous network found at the ends of long bones - allows space for blood vessles and making blood cells

43
Q

What are the two ways which bone grows?

A

Intramembranous and endochondral ossification

44
Q

How does intramembranous work?

A

Bone cells differentiate directly from embryonic mesenchyme and are organised to form a bone

45
Q

How does endochondral work?

A

The embryonic mesenchyme differentials to form hyelin cartilage model which is replaced by bone.

46
Q

What are the 2 types of bone marrow?

A

Red - Active marrow always making red blood cells

Yellow - Inactive marrow which can convert to red marrow.

Marrow cavity which has yellow marrow also has adipose tissue hence yellow

47
Q

Describe the funtion of lumps in bones.

A

Site at which white tendons are inserted into bone

48
Q

Function of smooth areas?

A

Points of articulation between bones

49
Q

Function of rough areas

A

Site of ligament or tendon insertion

50
Q

Function of grooves?

A

Wear and tear

51
Q

Function of holes?

A

Allow blood vessels or nerves to pass

52
Q

CT scan shows up soft tissue better than an MRI - True or False

A

False - CT used more for bones
