SKELETAL SYSTEM

QuestionAnswer
1. THE HEEL BONE IS CALLED Calcaneus
2. JOINTS: Are the places at which the bones come together
3. ANOTHER NAME FOR THE SPINAL COLUMN IS: Vertebral column
4. FINGER BONES ARE CALLED: Phalangers
5. THE LARGER OF THE TWO LOWER LEG BONES: Tibia
6. SCOLIOSIS: Lateral curvature of the spine
7. BONE CELLS THAT ABSORB AND REMOVE UNWANTED BONES TISSUE: Osteoclast
8. RECORD OF STRENGTH OF MUSCLE CONTRACTION: Electromyography
9. THE SMALLER OF THE TWO LOWER LEG BONES IS KNOWN AS: Fibula
10. THE SHOULDER BONE IS KNOWN AS: Scapula
11. SAC OF FLUID NEAR A JOINT: Bursa
12. SPONGY, POROUS BONE TISUE IS: Cancellous
13. WHEN YOU BEND THE ELBOW TO TOUCH YOUR SHOULDER, THE ACTION IS: Flexion
14. MUSCLES AND BONES: When a muscle contracts, it pulls a bone. Muscles ae attached to bones by tendons, which are made of elastic connective tissue. The tendon of a muscle merges with the periosteum that covers the bone.
15. MUSCLE LOCATIONS AND FUNCTIONS: The quadriceps femoris group is on the front of the thigh and extends the lower leg. The triceps brachii extends the forearm; its antagonist is the biceps brachii. The rectus abdominus is on the front of the abdomen and fleses the vertebral column.
16. MUSCLE TONE: Muscle tone is a state of slight contraction. Good muscle tone improves coordination andhelps maintain posture. The Cerebellum regulates muscle tone.
17. SOME OXYGEN MAY BE STORED WITHIN FIBERS BONDED TO THE PROTEIN: Myoglobin
18.AN ANTAGONIST TO A MUSCLE THAT FLEXES THE ARM WOULD BE A MUSCLE THAT: Extends the arm
19. THE AXON TERMINAL OF A MOTOR NEURON RELEASES: Acetylcholine
20. THE MOST ABUNDANT SOURCE OF ENERGY IN A MUSCLE FIBER IS: Creatine phosphate
21. THE MORE MOVABLE ATTACHMENT OF A MUSCLE TO A BONE IS CALLED THE: Insertion
22. GOOD MUSCLE TONE IS IMPORTANT TO: Maintain posture and produce body heat
23. MUSCLE FATIGUE IS THE RESULT OF THE LACK OF ___ AND THE PRODUCTION OF ____. osygen / lactic acid
24. NEUROMUSCULAR JUNCTION: The axon terminal is the end of the motor neuron. The sarcolemma contains cholinesterase. The synapse is the small space between the axon terminal and the sarcolemma.
25. EXERCISES: Increased heart rate transports oxygen to muscles more rapidly. Increased cell respiration produces more heat, ATP and carbon dioxide. Increased respiration is necessary to exhale excess carbon dioxide.
26. OXYGEN AND MUSCLE CONTRACTION: Oxygen is brought to muscle fibers by hemoglobin in red blood cells. Oxygen is needed for the complete breakdown of glucose in cell respiration. In the absence of oxygen, lactic acid is formed and causes fatigue.
27. DURING EXERCISE, THE BLOOD FLOW WITHIN A MUSCLE IS INCREASED BY: Vasodilation
28. THE PRODUCT OF CELL RESPIRATION THAT IS CONSIDERED A WASTE PRODUCT IS: Carbon dioxide
29. THE ORGAN SYSTEM THAT TRANSPORTS OXYGEN TO MUSCLES AND REMOVES CARBON DIOXIDE IS THE: Circulatory system
30. THE CONTRACTING PROTEINS WITHIN A MUSCLE FIBER ARE: Myosin and actin
31. WHEN A MUSCLE CONTRACTS, IT: Shortens and pulls a bone
32. MUSCLES ARE ATTACHED TO BONES BY: Tendons
33. THE VERTEBRAL COLUMN: The vetebral column supports the trunk and head. Thoracic vertebrae articulate with the posterior ends of the ribs. The hipbones articulate with the lumbar vertebrae
34.PROTECTIVE FUNCTION OF BONES: The vertebral column protects the spinal cord. The skull protects the brain, eyes and ears. Spongy bone in the flat and irregular bones protects the red bone marrow.
35. SYNOVIAL JOINTS: Joint surfaces are smooth because of the presence of articula cartilage. Bursas permit tendons to slide easily as a joint is moved. The fibrous connective tissue joint capsule encloses the joint.
36. IN THE LONG BONES OF A CHILD, THE PART OF THE BONE THAT IS ACTUALLY GROWING IS THE: Epiphyseal disc
37. THE HORMONES THAT REGULATE BLOOD CALCIUM LEVEL BY REGULATING CALCIUM INTAKE OR OUTPUT FROM BONES ARE: Calcitonin and parathyroid hormone
38. TISSUES OF THE SKELETAL SYSTEM: Bone matrix provides strength and stores excess calcium. The periosteum is made of fibrous connective tissue and anchors tendons and ligaments. Ligaments are made of fibrous connective tissue and conect bone to bone.
39. THE LARGEST BONES OF THE ARM AND THE LEG ARE THE: Humerus / femur
40. THE MINERALS THAT BECOME PART OF THE BONE MATRIX ARE: Calcium and phosphorus
41. THE CELLS THAT PRODUCE BONE MATRIX AND THOSE THAT REABSORB BONE MATRIX ARE CALLED: Osteoblast / osteoclasts
42. RED BONE MARROW IS FOUND IN THE: Marrow cavity of long bones
43. RED BONE MARROW PRODUCES THESE CELLS: Red blood cells White blood cells Platelets
44. THE MALLEUS, INCUS AND STAPES ARE WITHIN THE ___ BONE AND ARE CONCERNED WITH ___. Temporal bone / hearing
45. SUTURES ARE THE ___ JOINTS OF THE ___. Immovable / skull
46. THE FONTANELS OF BABY'S SKULL ARE MADE OF: Cartilage
47. THE VITAMIN NECESSARY FOR EFFICIENT ABSORPTION OF CALCIUM AND PHOSPHORUS BY THE SMALL INTESTINE IS: D
48. AN EXAMPLE OF A BALL AND SOCKET JOINT IS THE ONE BETWEEN THE: Femur and hipbone
49. FOR BONES, THE TERMS "EXERCISE" OR "STRESS" MEAN: Bearing weight
50. THESE BONES ARE ALL PART OF AXIAL SKELETON: Sternum Skull Sacrum
