25
What is the basic unit of your bones?
Osteons
26
Your Osteons contains tubes. What is the other name of these tubes?
Lamellae
27
What does your Lamellae do?
It helps resist torsion & stress
28
It holds your nerves & blood vessels (nourishment to the bone)
Central Canal
29
These are tiny oblong spaces/gaps that houses your Osteocytes
Lacunae
30
These are your mature bone cells.
Osteocytes Cells
31
What do your bone cells do?
They monitor & maintain your blood matrix.
32
What are 2 types of Osteocytes cells?
Osteoblasts & Osteoclasts cells
33
This type of Osteocytes cells are known to be "Bone building makers" & they secret like glue.
Osteoblasts Cells
34
What type of Osteocytes cells is known to be the "Bone Breakers" (process before producing a new bone)?
Osteoclasts Cells
35
It is responsible for initiating Bone Remodeling
Osteocytes Cells
36
This is known for its Resorption /tear-down process wherein, the Osteocytes release chemical signals & direct Osteoclasts to the site of the damage. Once they get there, they'll secret a collagen-digesting enzyme & acidic hydrogen-ion that dissolves the calcium phosphate, releasing its components back in the blood.
Bone Remodeling Process
37
What are the types of Fractures?
Closed (simple) & Open (compound) fractures.
38
What are the 2 types of Cartilage?
Hyaline & Fibrous Cartilage
39
What type of Cartilage is located in the nose, ears, and immovable joints?
Hyaline Cartilage
40
What type of Cartilage is found in the sponge stuff in your spine
Fibrous Cartilage
41
How many bones does your Skull have?
22 bones: - Cranium (3 cranial bones) - Facial bonesb(14)
42
What are the 8 Cranial bones?
1. Frontal bone 2. Parietal bone (pair of flat bones - each side of the head) 3. Temporal bone 4. Occipital bone 5. Sphenoid bone 6. Ethmoid bone
43
What are the 14 facial bones?
``` 1-2. Inferior Turbinal 3-4. Lacrinal Bones 5. Mandible 6-7 Maxilla 8-9 Nasal Bones 10-11 Palatine Bones 12.Vomer 13-14. Zygomatic bones ```
44
Where can you find the Hyoid bone (skull)?
In the chin area
45
Where do you find your 6 Auditory Ossicles?
In the ears.
46
What are your 6 Auditory Ossicles?
1. Malleus 2. Incus 3-6. Stapes in each ear.
47
It is responsible for supporting the axial bones.
Vertebral Column
48
How many vertebral bones are separated by intervertebral discs?
26 vertebral bones
49
What are the 5 (26) parts of Vertebral column?
1. Cervical (7 fusions) 2. Thoracic (12 f) 3. Lumbar Spine Sections (5 f) 4. Sacrum bones (5 f) 5. Coccyx bones (4 f)
50
What is the top of your Cervical Vertebrae (C1)?
Atlas Vertebra
51
What is the top of your Cervical Vertebrae (C1)?
Atlas Vertebra
52
What holds up the skull?
Atlas Vertebra
53
How many pairs of ribs are there in your Rib cage/thoracic cage?
12 pairs of ribs & a dagger like sternum
54
It protects your most vital organs (lungs, heart, liver..)
Thoracic cage/Ribcage
55
The meeting of 2 or more bones..
Joints/Articulations
56

62
What are the 3 types of Structural Classification of Joints?
1. Fibrous Joints 2. Cartilaginous Joints 3. Synovial Joints
63
This type of Structural Joint that is immovable and connects bones with dense fibrous connective tissue.
Fibrous Joints
64
The type of Structural joint that does not move much or very much slightly & lacks joint cavity. Unites bones using Cartilage.
Cartilaginous Joints
65
These are freely moveable joints. Band-like ligaments & separated by joint cavity.
