Laboratory 17 : Pelvic Girdle and Lower Limb Flashcards
What does the pelvic girdle include?
The pelvic girl includes two hip bones, commonly called the ossa coxae, that articulate with each other anteriorly at the pubic symphysis.
Where do the hip bones articulate with each other (anteriorly)?
Anteriorly at the pubic symphysis.
What constitutes the pelvis?
The pelvic girdle, sacrum, and coccyx.
What does the pelvis do?
Provides support for the trunk of the body and provides attachments for the lower limbs.
What does the pelvis support and protect?
The pelvis supports and protects the viscera in the pelvic region of the abdominal cavity.
What is the pelvic outlet?
Includes the coccyx, inferior border of the pubic symphysis and between the ischial tuberosities.
Why is the pelvic outlet important in females?
The pelvic outlet must be large enough to successfully accommodate the fetal head during delivery.
What does each acetabulum of hip bones articulate with?
Each acetabulum of a hip bone articulates with the head of the femur of a lower limb.
Which joint is more stable, hip or shoulder?
Hip joint.
What do the bones of the lower limb form?
The bones of the lower limb form the frame work of the thigh, leg, and foot.
What does the thigh represent anatomically?
Represents the region from hip to knee.
What does the leg represent anatomically?
Leg is from knee to ankle.
What does foot represent anatomically?
Foot is from ankle to toe.
What bone does the thigh represent?
Femur
What bone does the knee include?
Patella.
What bones does the leg include?
Fibula, Tibula
What bones does the foot include?
Seven tarsals, five metatarsals, and fourteen phalanges.
How many tarsals ?
Seven
How many metatarsals?
Five
How many phalanges in the foot
Fourteen
What do all the bones in the lower limb have in common?
These bones and muscles attached to them provide weight bearing support and locomotion and thus are considerably larger and possess more stable joints than those of an upper limb.
What does the pelvic girdle support?
Supports the majority of the weight of the head neck and trunk.
Where does the hip bone originate?
Three seperate ossification areas known as ilium, isichium, and pubis.
When are hip bones formed?
The ilium, isichuim and pubis are three bones in a child but eventually fuse into a single bone.
