    • Aerobic- with O2
    • Anarobic- without O2
  6. Define Tissue?
    Group of cells that perform a similar function

    • Lines internal and external body surfaces and protects the body. Some forms perform specialized functions
    • Secretion
    • Absorption
    • Diffusion

    Contracts when stimulated.
  10. Cardia Tissue?
    Found only within the heart. Unique capability of spontaneous contraction w/e external stimulation
  11. Smooth Muscle?
    • Found with in intestines and encircling blood vessels
    • Generally under control of the autonomic nervous system.
  12. Skeletal muscle ?
    allows movement and is generally under coluntary control - most abundant type. ( brain activated.)
  13. Nerve Tissue?
    Specialized Tiwwue that transmits electrical impulses throughought the body. ( spinal cord, peripheral nerves)
  14. Organ?
    structure made up of 2 or more kinds of tissue organized to perform a more complex function.
  15. System?
    Group of organs arranged to perform a more complex function than can any one organ alone. 11 major systems
  16. Tendon?
    Connects bones with Muscle
  17. Ligament
    Bone to Bone
  18. Floating Bone?
    Hyoid Bone
  19. Vertebral Column
    • 7- cervical
    • 12- thoracic
    • 5- lumbar
    • 5- sacral ( 5 fused)
    • 4 or 5- coccyx
  20. Thoracic Cage?
    • protects vital organs in the thorax
    • prevents collapse of the thorax during respiration.
  21. Appendical Skeleton?
    Consists of the bones of extremities
  22. Every bone connects to at least one other bone except?
    Hyoid bone.
  23. 3 Major classifications of joints?
    • Fibrous
    • Cartilaginous
    • Synovial- Contain synovial fluid allows movement between articulation bones accounts for most joings of appendiculat skeleton.
  24. Primary functions of the skeletal system?
    • movement
    • postural maintenance
    • heat protection
  25. Skeletal muscle
    Voluntary muscle- found through the body
  26. Cardiac muscle
    limited to the heart
  27. Smooth muscles
    Involvuntary muscles. intestines and surrounds blood vessles.
  28. What is the difference between Sensory nerves and Motor nerves?
    • Sensory- voluntary
    • Motor - Involuntay
  29. Organ of the Parasympotetic nervous system?
    Vegas Nerve
  30. Central nervous system?
    Bran spinal cord
  31. Peripheral nervous system?
    Collects info from both inside and outside the body. Relays info by AFFERENT fibers to the CNS and EFFERENT fibers from CNS to rest of body
  32. PADS
    Pia matter- arachnoid-dura- skull ( meningeal coverings of the brain and spinal cord.
  33. Dermatome
    Refers to skin surface area suppled by a single spinal nerve

  35. Organ and hormones of the sympothetic nervous system?
    Thoracis and lumber ganglia- Epinephrine and norepinephrine- alpha and beta receptors
  36. olfactory sense organs?
    Receptors lie in the mucosa and upper part of the nasal cavity. Nerve impulses interpreted by the brain as specific odors.
  37. Endocrine system?
    Bodies messenger system
  38. Hormones?
    Dissolved in blood plasma and quickly distributed throughout the body.
  39. Endocrine glands?
    Secrete hormones directly into the circulatory system.
  40. What does your adrenal glad secrete?
    spinephrine and norepinephrine- sympotetic nervous system
  41. what does your pancreas secrete ?( islets of langerhans)
    insulin and glucagon
  42. exocrine glads ( out)
    secrete substances such as sweat, saliva, tears mucus ect. pushing "stuff" out of the bloodstream.
  43. Receptor notes
    • Chemoreceptors respond to chemical stimuli
    • Barareceptors respond to pressure changes
    • alpha and beta receptors - neaurotransmitters and meds
  44. Define Metabolism
    Building up( anabolism) and breaking down ( catabolism) of biochems substances and produce energy.
  45. Paracardial sac?
    fibrous sac surrounding the heart.
  46. Endocardium?
    inside layer of the heart

    Pulm artery
  49. What veins does blood enter the heart from?
    Pulmonary veins
  50. Systemic Circulation?
    Blood enters heart at Pul veins into Left ven 1st- passes through left atrium into left ventrical and then into aotra. from aorta blood is pumped throughout the body.
  51. Point of bifurcation of the trachea?
  52. Ventilation is what kind of movement?
    mechanical movement

    Meds to break apart clots
  60. Define myocardium
    heart muscle
  61. define arteriovenous anastomoses ( av Stunts)
    Allows blood to flow from ateries to veins without passing through capillaries
  62. Which way to veins flow?
    Into the heart
