Lab Exam 3 Flashcards
Nondisplaced

Incomplete
Not broken all the way through
Linear
Break parallel to long axis of bone
Transverse
Perpendicular to long axis of bone
Spiral/Oblique
Spiral break (Common in Child Abuse)
Compound
Bone penetrates through skin
Simple
Bone does not penetrate skin
Avulsion
Complete severing of body part
Comminuted
Fracture of the distal end of the lateral forearm bone
Compression
Bone is squashed
Epiphyseal
Epiphysis is separated from diaphysis at epiphyseal plate
Greenstick
Partial fracture (One side of bone breaks & other side is bent)
Hairline
Fine crack in which bone remains aligned
Pathologic
Weakening of bone due to disease
Axial Skeleton
Middle skeleton (Skull, Sternum, Ribs, & Vertebrae)
Appendicular Skeleton
Appendage skeleton (Clavicle, Scapula, Arm Bones, Hip Bones, & Leg Bones)
Calvaria
Temporal & Parietal Bones
Cranial Base
Sphenoid, Temporal, & Occipital Bones
Hyaline Cartilage
Nose, larynx, trachea, bronchi, epiphyseal plate, & articular cartilages. (Makes up most of fetal skeleton until replaced)
Elastic Cartilage
Auricle or pinna, epiglottis, & external auditory meatus
Fibrous Cartilage
Intervertebral discs, pubic symphysis, articular discs in sternoclavicular & temporomandipular joints, glenodial labrum, & acetabular labrum
Conchae Bones
(Swirly bones in nose) Help control airflow into nose, cleaning & warming air that goes into lungs
Cervical Vertebrae
1st part, Neck area, C1-C7
Thoracic Vertebrae
2nd part, Upper back part, T1-T12
Lumbar Vertebrae
3rd part, Lower back, L1-L5
Sacrum
4th part, back of hip area, S1-S5
Coccyx
Tailbone
Integumentary
Skeletal system provides support; skin provides Vitamin D
Muscular
Skeletal system provides the levers and stores Ca needed for nervous system function; hormones regulate bone growth & calcium storage
Endocrine
Skeletal protects, stores Ca needed for hormonal messages; hormone regulates bone growth & calcium storage
Cardiovascular
Bone marrow provides site for blood cell formation; cardiovascular transports O & CO2 & nutrients
Lymphatic
Skeletal provides protection and support and is source of lymphocytes; lymphatic immune cells protect bone
Respiratory
Skeletal provides protection and support; respiratory provides O and eliminates CO2
Digestive
Skeletal provides protection and support; digestive provides nutrients
Urinary
Skeletal provides protection and support; urinary activates Vit D and eliminates nitrogenous waste.
Reproductive
Skeletal provides protection and support; reproductive provides some hormones needed for growth
Male Skull
Large Brow Ridge, Square Chin/Features, Sharper Angles
Female Skull
Not prominent brow bone, softer/rounder chin/features, rounder jaw
Adult Epiphysis
Full calcification, stays one piece
Child Epiphysis
No full calcification, top will fall off on child bone due to the cartilage decaying
Anterior Fontenelle
Top of head
Posterior Fontanelle
Back of head
Sphenoid Fontanelle
Side of head towards front
Mastoid Fontanelle
Side of head towards back
Fibrous Joint
Bones held together by dense connective tissue
Cartilaginous Joint
Bones held together by cartilage
Synovial Joints
Bones joined by ligaments with fluid filled joint cavity separating bone surfaces (Popping Joints)
Synarthrosis
Immobile joints, fibrous or cartilaginous
Amphiarthroses
Slightly mobile joints, fibrous or cartilaginous
Diarthroses
Freely mobile joints, all synovial
Gomphoses
Fibrous, peg in socket, ex. Tooth
Sutures
Fibrous, between skull bones
Syndesmoses
Fibrous, between tibia & fibula
Synchondroses
Cartilaginous, bones joined by hyaline cartilage
Symphyses
Cartilaginous, pads of fibrocartilage between articulating bones
Uniaxial
Synovial, bone moves in just one place or axis
Biaxial
Synovial, bone moves in two planes or axes
Multiaxial
Synovial, bone moves in multiple planes or axes
Plane Joints
Synovial, uniaxial, articular surface flat
Hinge Joint
Synovial, uniaxial, convex surface with concave depression
Pivot Joint
Synovial, uniaxial, bone with rounded surface fits into ligament ring
Condylar Joint
Synovial, biaxial, oval convex surface articulating with concave surface
Saddle Joint
Synovial, biaxial, convex & concave surfaces resembling saddle shape
Ball & Socket Joint
Synovial, multiaxial, spherical head of one bone fitting into cupcake like socket
Gliding
2 opposing surfaces sliding back and forth or side to side
Angular Motion
Increases or decreases angle between 2 bones
Flexion
Angular, movement in an anterior-posterior plane, brings bones closer together
Extension
Angular, movement in an anterior-posterior plane, brings bones further apart
Hyperextension
Angular, joint extender more than 180 degrees
Lateral Flexion
Angular, trunk of body moving in coronal plane laterally
Abduction
Angular, lateral movement of body part away from midline
Adduction
Angular, medial movement of body part toward midline
Circumduction
Proximal end of appendage relatively stationary, distal end makes a circular motion, movement makes an imaginary cone shape
Rotation Motion
Bone pivots on its own longitude axis
Lateral Rotation
Rotation, Turns anterior surface of bone laterally
Medial Rotation
Rotation, Turns anterior surface of bone medially
Pronation
Rotation, medial rotation of forearm so palm of hand posterior
Supination
Rotation, lateral rotation of forearm so palm of hand anterior
Special Movements
Movements that do not fit in another category
Depression
Special, inferior movement of a body part
Elevation
Special, superior movement of a body part
