Q

Protrusion

A

Protrusion – moving anteriorly

25
Q

Retrusion

A

Retrusion – moving posteriorly

26
Q

✓Epidermis

A

✓Epidermis: Stratified epithelium with keratin on top. Renewed every 25- 45 days. Avascular layer.

27
Q

✓Dermis.

A

✓Dermis: made up of collagen & elastic fibers. Gives strength & toughness to the skin. Contains hair follicles, arrector pili muscle & sebaceous glands.

28
Q

Superficial fascia (subcutaneous tissue)

A

Superficial fascia (subcutaneous tissue): • Composed of loose connective tissue + fat • Location: Between dermis & deep fascia

29
Q

Deep fascia

A

Reduces friction with movement

• Devoid of fat

▪ Protects the muscles blood vessels and nerves from getting sheared with movement

▪ separates muscles into compartments

30
Q

Intermuscular septum

A

Extend deep from surrounding fascial sleeve to attach to bones.

31
Q

Arteries

A

Carry blood away from heart • 3 types – elastic, muscular, arterioles

32
Q

Veins

A

Veins • Return low-oxygenated blood towards heart • Valves –unidirectional flow

33
Q

Capillaries

A

Capillaries • Minute vessels form network btw arterioles and venules • Sinusoids

34
Q

Arteriosclerosis

A

Arteriosclerosis/ hardening of arteries: thickening & loss of elasticity of arterial wall.

35
Q

Atherosclerosis

A

Atherosclerosis (build up of fat in arterial walls)- form of arteriosclerosis

36
Q

Lymph-

A

Lymph- Clear & watery fluid. Similar in composition to blood plasma.

37
Q

Functions of lymphoid system:

A

Functions of lymphoid system: • Drains surplus tissue fluid and leaked plasma proteins(LYMPH) • Removal of cellular debris and infection • Absorption and transport of dietary fat • Defense mechanism

38
Q

The lymphoid system consists of the following structures:

A

The lymphoid system consists of the following structures: ✓ Lymphatic plexuses ✓Lymphatic vessels (exceptions teeth, bone, bone marrow, and the entire central nervoussystem ✓ Lymph nodes ✓ Lymphocytes ✓Lymphoid organs: spleen, thymus, lymph node

39
Q

• Lymphangitis and lymphadenitis: Secondary inflammation of lymphatic vessels and lymph nodes

A

• Lymphangitis and lymphadenitis: Secondary inflammation of lymphatic vessels and lymph nodes

40
Q

Lymphedema

A

Lymphedema (the accumulation of interstitial fluid) occurs when lymph is not drained from an area of the body.

41
Q

A joint or articulation (or articular surface) is

A

A joint or articulation (or articular surface) is the connection made between bones in the body which link the skeletal system into a functional whole.

42
Q

Fibrous joint

Sutures

A

Sutures (found in skull) 1. Immovable 2. Types: Plane, Squamous, serrate etc.

43
Q

Fibrous joint

Syndesmosis

A

Syndesmosis 1. Bones are united by sheet of fibrous tissue 2. Movement is possible. Eg; Middle radio ulnar joint , middle & Inferior tibiofibular joint

44
Q

Fibrous joints

Gomphosis

A

Gomphosis 1. Peg-like fibrous process 2. Fits into a socket

45
Q

Synovial joints

A

Two or more bones approximate, held together by capsule, strengthened by ligaments and lubricated by synovial fluid • Highly mobile

46
Q

Bursae

A

Closed sac of serous membrane • Normally collapse, wall oppose with thin film of lubricating fluid • Enables free movements • Synovial tendon sheaths – elongated bursae that wrap around tendon

47
Q

Secondary cartilage joints

A

Closed sac of serous membrane • Normally collapse, wall oppose with thin film of lubricating fluid • Enables free movements • Synovial tendon sheaths – elongated bursae that wrap around tendon

48
Q

Articular cartilage

A

Avascular and is reliant upon the passive diffusion of nutrients from the synovial fluid. • Prevents friction between the bones • Few synovial joints of the body have a fibrocartilage structure located between the articulating bones. • E.g. Articular disc, present in the temporomandibular joint or meniscus, present in the knee joint (Medial meniscus and lateral meniscus)

49
Q

Plane synovial joints

A

Permit gliding / sliding • Surfaces are flat • E.g., intercarpal joints, intertarsal joints, acromioclavicular joint

50
Q

Hinge joint

A

Hinge joint • One articular surface is convex, and the other surface is curved • Strong collateral ligaments • Movements in one axis • E.g., elbow joint, knee joint, ankle joint, interphalangeal joint

51
Q

Pivot joint

A

Pivot joint • Central bony pivot (peg) surrounded by an osseoligamentous ring • Movements in one axis • e.g., Superior radio-ulnar joint, Atlanto-axial joint.

52
Q

Condyloid joints

A

Condyloid joints • Convex surface articulating against concave surface • Movement across two axes • E.g., Metacarpophalangeal joint

53
Q

Saddle joint

A

Saddle joint • Surfaces are concavo-convex • Movement around two axes • E.g., First carpometacarpal joint

54

55
Q

56
Q

Rheumatoid arthritis

A

Rheumatoid arthritis • Inflammatory disease • Autoimmune disease • Immune system attacks the synovial membranes and articular structures, leading to deformities and disability. • Most common symptoms are joint swelling, stiffness, and pain.

57
