Skeletal System part 3 Flashcards
The leg has two bones
Tibia and Fibula
The female inlet is ______ and more _______
larger, circular
as a whole is shallower, and the bones are lighter and thinner
Female Pelvis
The female ilia flare more _________
laterally
The _________ is shorter and less curved
female sacrum
are shorter and farther apart; thus the outlet is larger
female ischial spines
more rounded because the angle of the pubic arch is greater
female pubic arch
The thigh has one bone
Femur
the only bone in the thigh
It is the heaviest, strongest bone in the body
Femur
Its ___________ has a ball-like head, a neck and greater and lesser trochanters
proximal end
Distally on the femur are the lateral and medial _________ which articulate with the tibia below
epicondyles
Is larger and more medial leg bone
tibia or shin bone
is thin and sticklike leg bone
fibula
At the proximal end, the medial and lateral ___________ articulate with the distal end of the femur to form the knee joint
condyles
Distally, a process called the _________ ________ forms the inner bulge of the ankle
medial malleolus
The distal end of the fibula called the ________ ________ forms the outer part of the ankle
lateral malleolus
3 types of bones in the feet
Tarsus , Metatarsals, and Phalanges
Also known as the cluster of ankle bones
Tarsus
Also known as the cluster of sole bones
metatarsals
Also known as the toe bone
Phalanges
Supports our body weight
Serves as a lever that allows us to propel our bodies forward when we walk and run
foot
Is composed of seven tarsal bones
Body weight is carried mostly by the two largest tarsals, the calcaneous or heeling bone and the talus
Tarsus
Body weight is carried mostly by the two largest tarsals, the _________________ and the _________
calcaneous or heeling bone and talus
seven tarsal bones
Medial cuneiform
calcaneous
Intermediate cuneiform
Navicular
Talus
Lateral cuneiform
Cuboid
There are __ metatarsals from the sole
5
___ phalanges form the toes
14
Bones of the foot are arranged to form three strong arches
Two longitudinal
One transverse
Articulations of bones. They Hold bones together
and Allow for mobility
Joints
Ways joints are classified
Functionally
Structurally
With one exception (the ______ ______ of the neck) every bone in the body forms a joint with at least one other bone.
hyoid bone
immovable joints
Synarthroses
slightly moveable joints
Amphiarthroses
freely moveable joints
Diarthroses
