Q

Functions of the Epithelial Tissue?

A
  • Provide physical protection (covers exposed surfaces)
  • Control permeability
  • Provide sensation
  • Produce specialised secretions (lines internal passageways and chambers)
  • Forms secretory glands

Q

Role of endocrine glands?

A

Secrete hormones (chemical messagers) or their inactive precursors into the interstitial fluid that then enter the bloodstream for distribution.

37
Rotation
Rotation around the long axis of a joint
38

Palm faces posterior
39
Supination

40
Functions of the skeleton
- Support - Movement - Protection - Storage - Red blood cell info
41
Name the 2 types of bone tissue
Compact bone, cancellous
42
Name the different bone classes
Long bone, short bone, flat bone and irregular bone
43
Axial Skeleton
- Bones of the core (Skull, sternum, ribs, vertebral, column, sacrum, coccyx) - protection of vital organs
44
Appendicular Skeleton
- Bones of the limbs - Most important for movement
45
Name the vertebral column divisions and the number
Cervical 7, Thoracic 12, Lumbar 5, Sacrum and coccyx
46
What bone is the Humerus/Femur
Single proximal long bone
47
What bones are the Ulna and Radius/ Tibia and Fibula
Two distal long bones
48
Bones in the hand
- carpals (8) - Metacarpals (5) - Phalanges (14- only 2 in the thumb)
49
Bones in the foot
- Tarsals (7) - Metatarsals (5) - Phalanges (14)
50
How do the limbs attach to the axial skeleton?
Pectoral (shoulder) girdle and Pelvic girdle
51
What makes up the pectoral girdle?
Clavicle and Scapula
52
What makes up the Pelvic girdle?
Hip bones ( ilium, pubis, ischium) , sacrum, and coccyx
53
Difference between biological male and female pelvic anatomy?
- Pelvic cavity of biological females more circular - Pelvic outlet more open in biological females
54
The skull includes:
Cranium, facial bones, cranial bones
55
Bone has 2 extracellular components: Write the percentages along with it.
Organic (33%) and Inorganic (67%)
56
Name the 4 different cells in bone:
- Osteogenic cells - Osteoblasts - Osteocytes - Osteoclasts
57
Osteon
Provide a pathway for nutrients to get cells in the ECM
58
Central canal
Contains blood vessel and nerves
59
Lamellae
A series of cylinders formed of ECM around the central canal
60
Lacunae
Lakes for osteocytes
61
Canaliculi
Channels for nutrients through ECM
62
Bone remodelling
- Allows bones to grow (appositional growth) - Osteoblasts add bone matrix in lamellae - Osteoclasts remove bone from medullary cavity
63
Bone homeostasis
- Balance of OB and OC activity - Bone is constantly being formed/ destroyed
64
What happens if homeostasis isn't maintained?
- Body has requirements to maintain homeostasis - Get an imbalance in osteoblastic/ osteoclastic activity
65
Osteoporosis
- Loss of cortical bone - In cancellous bone trabeculae become thinner - Compression fractures of vertebrae
66
Why do only some people get osteoporosis?
- biological females more at risk - Lifestyle factors - Depends on your start point
