CSCS Exam Practice Questions 2018, NSCA CSCS
UPDATED ACTUAL QUESTIONS AND CORRECT ANSWERS
Skeletal System Composition 206 Bones in adult body
provides leverage, support, and protection
Pulled on by muscles to allow the body to push or pull against external objects
Axial Skeleton Skull, Vertebral Column, Ribs and Sternum
Appendicular Skeleton Shoulder Girdle; bones of arms, wrists, hands, and pelvic girdle; bones of legs,
ankles, and feet
Joints Junctions of bones
Fibrous Joint Allows virtually no movement (Sutures of skull)
Cartilaginous Joint Allows limited movement (intervetebral)
Synovial Joint Allows considerable movement (elbows/knees)
Uniaxial Hinge, rotate around one axis (elbow)
Biaxial Operate in two perpendicular planes (ankle/wrist)
Multiaxial Allow movement in all three axes (shoulder/hip)
, Vertebral Column Cervical 7 (lordotic curve)
Thoracic 12 (Kyphotic curve)
Lumbar 5 (Lordotic)
Sacral 5 ( Kyphotic)
Coccygeal 3-5
Curves help to distribute forces
Muscle Tissue Epimysium (outer layer)
Perimysium (surrounding group of fibers/fascicules)
Endomysium (surrounding individual fibers)
Fascia Delicate "cobwebby" tissue
Motor Unit Motor Neuron and the muscle fibers it innervates
Typically several hundred muscle fibers in a single motor unit
Sarcolemma The plasma membrane of a cell
Transverse Tubules Connect to plasma membrane to interior
Action potentials travel through
Ensures AP excites all parts of the muscle fiber at the same time
Sarcoplasm (muscle cytoplasm) Glycogen, myoglobin, mitochondrion
Myofibrils Contractile organelles
Extend length of muscle fiber
Sarcoplasmic Reticulum Membranous sacs around each myofibril
Stores Calcium ions (Ca2+)
Release of Ca2+ triggers muscle contraction
Filaments Function in the contractile process
Thick and thin filaments
2 thin for every 1 thick
Sarcomere Compartments of arranged filaments
Basic functional unit of a myofibril
