Chapter 1- Intro to Osteology Flashcards
Osteology-Structures that attach to (muscles/tendons, ligaments..)
a large rounded projection/process/eminence
Tuberosity
Osteology-Structures that attach to (muscles/tendons, ligaments..)
a very large, blunt, irregularly shaped process( e.g on the femur)
Trochanter
Osteology-Structures that attach to (muscles/tendons, ligaments..)
a narrow ridge of bone
Crest
Osteology-Structures that attach to (muscles/tendons, ligaments..)
a narrow ridge of bone, less prominent than crest
Line
Osteology-Structures that attach to (muscles/tendons, ligaments..)
a sharp, slender, often pointed projection
Spine
Osteology-Structures that attach to (muscles/tendons, ligaments..)
a raised area on or above a condyle
(condyle - a rounded articular projection)
epicondyle
Osteology-Structures that attach to (muscles/tendons, ligaments..)
an arm like bar of bone
Ramus
Osteology-Structures that attach to (muscles/tendons, ligaments..)
the principle mass of a structure (big portion of a bone)
Body
Osteology-Structures that attach helps the form joints
the location at which 2 or more bones make contact
Joint
Osteology-Structures that attach helps the form joints
-a rounded articular projection- part of the bone
Condyle
Osteology-Structures that attach helps the form joints
a bony expansion carried on a narrow neck
head
Osteology-Structures that attach helps the form joints
a smooth nearly flat articular surface
Facet
Osteology-Structures that allow things to pass through (muscles, nerves, blood vessels )
a canal like passageway (ear hole)
meatus
Osteology-Structures that allow things to pass through (muscles, nerves, blood vessels )
a cavity within a bone , filled with air and lined with mucous membrane
Sinus
Osteology-Structures that allow things to pass through (muscles, nerves, blood vessels)
a shallow depression or hollow generally in a bone
Fossa
e.g iliac fossa
Osteology-Structures that allow things to pass through (muscles, nerves, blood vessels)
a furrow
Groove
Osteology-Structures that allow things to pass through (muscles, nerves, blood vessels)
a narrow, slit-like opening
Fissure
e.g longtitudal fissure in the brain
Osteology-Structures that allow things to pass through (muscles, nerves, blood vessels)
a round/oval opening through bone
Foramen
Osteology-Structures that allow things to pass through (muscles, nerves, blood vessels)
an indentation is ——
a notch
Osteology-Structures that allow things to pass through (muscles, nerves, blood vessels)
a small rounded projection/process/eminence
Tubercle
The ———has a triangle-Shaped ———bone in the tendon of the quadricep.
patella
sesamoid
The patella embedded in the tendon
The largest sesamoid bone in the body is the ———
Patella
Looking at the anterior view of the patella , it has
1)——- which is a flat superior—–, 2)——–which is the more pointed inferior edge.
1) base - it is a flat superior edge
2) apex - it pointed inferior ridge
Posterior view of the patella :
1)———– 2) ———3)——-4)——–
- Vertical ridge
- medial articular facets
- lateral articular facets
What does the facets used for ?
It is used for articulation
Facets articulates with the patellar surface of the ———-and the ——– and ——-condyles of the femur.
- femur
- medial
- lateral
Tibia is called ——- ——-, primary ——– ——– bone of the leg. The fibula carries —–body weight.
- shin bone
- weight bearing
- 1/6th
The Tibiofemoral and Patellafemoral called the ——- ——–.
Knee Joint
The knee Joint has 3 articulations ;
- Lateral condyle of the tibia articulates with the lateral femoral
condyle. - Medial condyle of the tibia articulates with medial femoral
condyle - Patella articulates with the femur
The avaialble movement foe the knee joint:
- Flexion
- flexion
- extension
- internal rotation (limited)
- external rotation (limited)
- rotation occurs when knee is flexed
When the knees is flexed, the ——can rotate——- and ——
- tibia
- medially
- laterally
——- is lateral deviation of the distal bone of a joint, and is called —– ——-?
- Valgus
- Knocked knee
Genu Valgum means --------- and its variations : 1. Valgus--- 2. Valgus----- 3.Valugs-------
- knocked knee (feet are apart)
1. Vlagus knee
2. Valugs force
3. Valugs orientation/position
——–is the medial deviation of the distal bone of joint.
and it’s variations and it is known as ——
- Varus (feet are close together)
- Bow legged
What does genu varum means ? and it's variations 1. Varus ------ 2.Varus----- 3. Varus-----
- knee
- force
- orientation/position
Structure that help form joints aka ———–
