Coxae
Hip
Os
Bone
Inter
Between
What are the functions of a skeleton
Protects soft tissues, bears weight and acts as a lever to facilitate movement
What is the axial skeleton
Brain, spine chord, ribs
What is the appendicular skeleton
everything else (including hips)
What is a ligament
Join bones together
What is a tendon
Joins skeletal muscle to bone
What are bone features
Partsof a bone
What is an articulating surface
Ligament surface
What is a malleolus
Anklebone
What are the boundaries of the thoracic cavity
ribs
what is the scapula
shoulder bone
what is the clavicle
collarbone
What is the os coxae and what bones are fused together to form it
hip bones - lilium, ischium and pubus fused together to form the hip bone
What is the humerous
The arm bone
what is the radius
froearm bone
What is the ulna
forearm bone
What are the carpals
palm bones
What are metacarples
lower finger bones
What are the phalanges
upper finger bones
What is the femur
thighbone
What is the patella
the weird knee bone
what is the fibula and tibia
lower leg bones
What are the metatarsals
Lower toe bones
What are the phalanges
Upper toe bones
What are the factors affecting stability
Mobility, size, muscle points of attachment and ligament attachment (more ligament = more stability)
What is a multiaxial diarthrotic joint
can move in multiple planes and is freely movable
Whereis the sacroilliac joint
between the sacrum and illium
What is the amphiarthrotic joint
limited movement
What is the acetabulum
junction between three bones
What is common with all vertebrates
Has a backbone
Why is the spinal chord so protected
because the spinal chord is part of the CNS
What is a face that are the difference between superior and inferior vertebrae
Small
C1 - C6 have transverse axis to protect the brain blood supply
What are the thoracis vertebra
Long spinous process
What is a spinal process
pointy thing on the vertebra
What is the lumbar vertebra
short process, big and heavy
What are sacral bones
fused vertebra
What are the structure of bones
Compact outside vs spiny inside
What happens when bone stops growing
Plate turns into a line
What are compact bones made of
Central canal with centrixes around it
Why do compact bones have a multitude of shapes
For strength meaning there are no lines of stress
What is a lacuna
space with an osteocyte in it (bone cell)
What is the spongy bone made of
Matrix where marrow resides
What are osteoblasts
Builds bones
What are osteocytes
Function as a bone cell
What are osteoclasts
Destroy bones via bone resportion
What is a tubercle
Bone feature that attaches tendons/muscles
