The Appendicular Skeleton flash card

Deltoid tuberosity

a raised area on lateral surface of humerus to which deltoid muscle attaches

humerous

arm bone

Clavicle and scapula

bones of the shoulder girdle

Radius and Ulna

Forearm bones

Acromion

scapular region to which the clavicle connects

Scapula

shoulder girdle bone that is unattached to the axial skeleton

Clavicle

shoulder girdle bone that articulates with and transmits forces to the ebony thorax. Also know as the collarbone.

Glenoid Cavity

depression in the scapula that articulates with the humerus

Coracoid process

process above the glenoid cavity that permits muscle attachment

Trochlea

distal condyle of the humerus that articulates with the ulna.

Ulna

medial bone of forearm in anatomical position.

capitulum

rounded knob on the humerus; adjoins the radius

Coronoid Fossa

anterior depression superior to the trochlea, which receives part of the ulna when the forearm is flexed

Ulna

Forearm bone involved in formation of the elbow joint

carpals

wrist bones

phalanges

finger bones

metacarpals

heads of these bones form the knucles

scapula and sternum

bones that articulate with the clavicle

How is the arm held clear of the widest dimension of the thoracic cage

the clavicle acts as a strut to hold the glenoid cavity of the scapula(therefore the arm) laterally away from the narrowest dimension of the rib cage.

What is the total number of phalanges in the hand?

What is the total numbers of carpals in the wrist

Name the carpals (medial to lateral) in the proximal row.

pisiform, triquetral, lunate, scaphoid

Name the carpals in the distal row (medial to lateral)

hamate, capitate, trapezoid, trapezium

The Humerus is a right bone in a posterior view

…

The radius and ulna are right bones in an anterior view.

…

Pectoral bones

Flexibility most important
Light weight
Insecure axial and limb attachment

Pelvic Bones

Massive,
Secure axial and limb attachements
weight bearing most important

What organs are protected at least in part by the pelvic girdle

Uterus(female), urinary bladder, small instestine, rectum.

Distinguis between the true pelvis and the false pelvis

The true pelvis is the region inferior to the pelvic brim, which is encircled by bone. The false pelvis is the area medial to the flarin iliac bones and lies superior to the pelvic brim.

Deduce why the pelvic bone of a four-legged animal such as the cat or the pig are much less massive than those of the human.

The pelvic girdle does not have to carry the entire weight of the trunk in the quadruped animal

A persons instinctively curls over his abdominal area in times of danger ..

abdominal area organs receive the least protection from the skeletal system…

For what anatomical reason do many woman appear to be slightly knock-kneed

the pelvis is broader and the acetabula and ilia are more laterally positioned. Thus the femur runs downward to the knee more obliquely than in the male.

How might this anatomical arrangement contribute to knee injuries in female athletes

the more oblique angle in female causes greater fores on the anterior cruciate ligament ACL during knee rotation and the smaller the female intercondylar notch can pinch the ACL during twisting or hyperextended movements. Both events can cause a tear rupture of the ACL

What does fallen arches mean

a weaking of the tendons and ligaments supporting the arches of the food.

Fuse to form the coxal bone

ilium, ischium and pubis

sit down bone of the coxal bone

ischium

point where the coxal bones join anteriorly

pubic symphysis

superiormost margin of the coxal bone

iliac crest

deep socket in the coxal bone that receives the head of the thigh bone

acetabulum

joint between axial skeleton and pelvic girdle

sacroiliac joint

longest strongest bone in body

femur

thing lateral leg bone

fibula

heavy medial leg bone

tibia

medial ankle projection

medial malleolus

lateral ankle projection

lateral malleolus

largest tarsal bone

calcaneus

ankle bones

tarsals

bones forming the instep of the foot

metatarsals

opening in hip bone formed by the public and ischial rami

obturator foramen

sites of muscles attachment on the proximal femur

gluteal tuberosity and greater and lesser trochanters

tarsal bone that sits on the calcaneus

talus

weight bearing bone of the leg

tibia

tarsal bone that articulates with the tibia

talus

What are the 5 parts of the appendicular skeleton?

The bones that contribute to the appendicular skeleton include the bones of the hands, feet, upper extremity, lower extremity, shoulder girdle, and pelvic bonespelvic bonesThe hip bone (os coxae, innominate bone, pelvic bone or coxal bone) is a large irregular bone, constricted in the center and expanded above and below. In some vertebrates (including humans before puberty) it is composed of three parts: the ilium, ischium, and the pubis.https://en.wikipedia.org › wiki › Hip_boneHip bone - Wikipedia.

What are the appendicular skeleton in the body?

The appendicular skeleton is one of two major bone groups in the body, the other being the axial skeleton. The appendicular skeleton is comprised of the upper and lower extremities, which include the shoulder girdle and pelvis.

What is appendicular skeleton quizlet?

Appendicular Skeleton. Consists of the bones of the upper and lower limbs, together with the shoulder girdle and the pelvic girdle. The bones of the limbs are attached to the axial skeleton by the means of the shoulder girdle and the pelvic girdle. Shoulder Girdle. Consists of the clavicle and the scapula.
