Chapter 8 Flashcards
The appendicular skeleton has this many bones
126
Appendicular skeleton consists of
bones of the upper and lower limbs including girdles that attach them to the axial skeleton
The two pectoral (shoulder) girdles include
the clavicle (collar bone) and scapula (shoulder blade)
Medial (sternal) end of the clavicle articulates with the
manubrium of the sternum
Lateral (acromial) end articulates with
the acromion of the scapula
The scapula/shoulder blade is located
in the superior part of the posterior thorax between the second and seventh ribs
The scapulas attachment point for the humerus
glenoid cavity
the radius is located
on the thumb side (lateral)
the ulna is located
on the pinky side
How many bones are in the carpal (wrist)
8 bones
The proximal row of carpal bones
schaphoid, lunate, triquetrum, pisiform
The distral row of the carpal bones
trapezium, trapezoid, capitate, hammate
Metacarpals
hand bones
Numbering the fingers starts with the
thumb
The phalanges are broken down into 3 sections
proximal, middle and distal
The pelvic bone is made up of two hip bones
os coxa and coxal bones
Each hip bone is made up of three individual bones
the ilium, the ischium and the pubis
Pubic symphysis
where the two pelvic hip bones articulate
the 3 individual hip bones fuse into one hip bone by age
23
The head of the femur articulates with the (1) of the hip bone as a (2)
(1) acetabulum (2) ball and socket joint
The pelvis is devided into a superior and an inferior portion by the (1) where the abdomen meets the pelvic cavity
pelvic brim
The area of the bony pelvis superior to the pelvic brim is known as the
false (greater) pelvis
the area of the bony pelvis inferior to the pelvic brim is known as the
true (lesser) pelvis
Bones of the male pelvis are ususally
larger and heavier
The female pelvis is …. than that of the male
wider and shallower
the proximal end (head) of the femur inserts inot the
acetabulum of the hip bone (hip joint)
The distal end of the femur articulates with the
tibia (shinbone/knee joint) and patella (kneecap)
The lower leg consists of the
tibia and fibula
The tibias proximal end articulates with the
femur
the tibias distal end articulates with the
talus bone of the ankle
the tibial tuberosity on the anterior surface is the point of attachement for the
patellar ligament
the tarsus (ankle) contains #
7 tarsal bones
the metatarsus (foot bone) contains #
5 metatarsal bones
The foot has … arches
2
The 2 foot arches are called
the longitudinal arch and transverse arch
the purpose of the arch in the foot
support weight of the body, provide leverage while walking and distribute the body’s weight over the foot.
curvatures obvious at birth
thoracic and sacral
secondary curvatures
cervical and lumber
