Biomechanics Exam 1
>600 - Answer-# major muscles in the adult human body
206 - Answer-# bones in body (with over 1/2 in hands and feet)
43 - Answer-# major joints of the appendages
50-100 - Answer-# trillion cells
60,000 - Answer-miles of blood vessels
biomechanics - Answer-the mechanics of biological and especially muscular activity (as in locomotion or
exercise) and the scientific study of this
statics - Answer-mechanics dealing with forces producing equilibrium
dynamics - Answer-mechanics that deals with forces and their relation to motion
,kinematics - Answer-the form, pattern, or sequencing of movement with respect to time (displacement,
velocity, and acceleration) without taking into account the forces that produced the motion
kinetics - Answer-the study of the action of forces acting on the body
kinesiology - Answer-the study of human movement (AT, biomechanics, exercise phys, motor behavior,
sports psych)
anthropometry - Answer-the science that defines physical measurements of a person's size, form, and
functional capabilities
ergonomics (occupational) - Answer-study of the body in order to obtain maximum performance,
resolve disabilities, or design tasks/activities that can be performed without risk of injury
ie.) seat design, workplace setup, hand tool design, lifting strategies
0.2248 lbs - Answer-1 N =
bone - Answer--growth and development is a continuous and regulated process
-the material constituents and structural organization influence ways in which it responds to mechanical
loading
-material that is strong relative to its light weight
wolff's law - Answer-changes in bone structure occur with changes in function
--affect diameter width, mineral content, and density
bone atrophy - Answer-loss of bone mass and strength
, ie.)astronauts
stress fracture - Answer-a partial or complete bone fracture that results from repeated application of a
stress lower than the stress required in order to fracture the bone in a single loading
axial - Answer-primary mode of loading where the subject encounters tension and compression
axial, bending, shear, torsion - Answer-5 primary modes of loading
axial - Answer-skeleton that includes the skull, vertebrae, sternum and ribs
-80 bones
appendicular - Answer-skeleton that includes pectoral girdle, upper limbs, pelvic girdle, lower limbs
-126 bones
short bones - Answer-bones that are usually equal in length and width
-include wrist and foot bones where strength is required and mobility is less necessary
flat bones - Answer-bones that are generally thin, flat, and sometimes curved
-examples: skull, scapula, sternum, and ribs
-generally used for protection
long bones - Answer-bones that are much longer than they are wide and have an elongated shape.
-examples: femur, tibia, fibula, humerus, radius, ulna, fingers, toes
-provide levers for movement
