Chapter 7 Skeletal System Flashcards
Ilium
Largest and upper most part of the hip bone.
It flares outward, forming the prominence of the hip
Pelvis
The sacrum. coccyx, and pelvic girdle
Pubis
Anterior portion of the hip bone
Periosteum
Very tough membrane around bone
Very vascular
Spins off and connects with bone to become a tendon
Helps to form and repair blood tissue
Medullary Cavity
Inner middle part of the hollow long tube in long bones
Hinge Joint
Where the convex curve of one bone fits into the concave curve of another, it makes a joint that only moves one plane. (Like the elbow)
Hyoid bone
Only free floating bone in the body. Below the chin, Supports and helps with movement of the tongue

Lacrimal, Nasal, Inferior Nasal Conchae, Vomer, Zygomatic, Maxillae, Palantine, Mandible
Bones of the Face
Lacrimal (2), Nasal (2), Interior Nasal Conchae (2), Vomer (1) Zygomatic (2), Maxillae (2), Palantine (2) Mandible (1)
Cranium
Protects the brain
Foramen
Hole
7, 12, 5
7 Cervical Vertebrae, 12 Thoracic Vertebrae, 5 Lumbar
How many True Ribs
7 Pairs
How many False Ribs
5 Pairs
How Many Floating Ribs
2 Pair, sometimes 3
Pelvic Girdle
Hip area
All ribs connect to…
the vertebral column
What is the purpose of the rib cage?
To protect vital organs
What is the function of the vertebral column
To protect and support
Malleus
The first middle ear bone
Incus
The second middle ear bone
Stapes
The third middle ear bone (and the smallest in the body(
What does the pelvic girdle include?
Anteriorly it connects the coxal and innominate bones, with the sacrum bone posteriorly
What does the pelvic girdle include?
Hip bones, Pelvic bones (anteriorly) and the sacrum (posteriorly)
What is the function of the pelvic girdle?
Supports the trunk
Provides attachments for lower limbs
Protects the urinary bladder, distal end of the upper intestines, and the internal reproductive organs
Coxa
Hip bone / hip joint
Manubrium
Near the top of the sternum
Vertebronchondra
Includes the false and floating ribs
Hyaline Cartilage
Connects cartilagenous joints
Coronal Structure
Connects the frontal and parietal because at birth they do not meet
How many tarsal bones are there?
7
Where is the ethmoid sinus
By the tear ducts
Osteoblasts
Immature bone cells
The brick layers
Works with osteocytes to make strong bones
When surrounded, makes osteocytes
Osteocytes
Mature bone cells Assist in bone repair Keep bones health Maintain structure by recycling Work with osteoblasts to make strong bones
Osteoclasts
Large and multi-nucleated Act in clusters Function is to breakdown calcified matrix Short life span Tunnel into old blood tissue
Endochondral Ossification
1st, cartilage develops. Then bone formation begins. Last, overtime the plates will close so we stop growing
