Which of the following best describes the attachment of a tendon to a bone that does not move:
a) origin
b) suture
c) synovial joint
d) insertion
Correct!!!
Which of the following represents the most abundant intermediate filament:
a) keratin
b) vimentin
c) neurofilament
d) actin
e) two of the above
I read that it was vimentin...but it does seem a bit counter-intuitive...I was hoping someone could confirm this!!!
Which of the following is the best description of type II A muscle fiber:
a) It is fast twitch, with large amounts of mitochondria and myoglobin.
b) It is slow twitch, with large amounts of myoglobin/mitochondria, and is the most fatigue resistant
c) It is fast twitch, therefore fatigues easily, and has low amounts of myoglobin and mitochondria
d) It is fast twitch, fatigue resistant, with large amounts of myoglobin and mitochondria.
e) none of the above
A and D are essentially the same thing...but D is better because typeII A is indeed fatigue resistant.
Sarcoma is:
a) Can be used interchangebly with carcinoma
b) Cancer of the epithelial tissue
c) Cancer of connective tissue
d) Cancer of the skin
e) two of the above
Correct!!!
Which of the following are granular leukocytes:
a) Basophils, Monocytes, Eosinophils
b) Macrophages, Lymphocytes, Mast cells
c) Natural Killer Cells, Basophils, Monocytes
d) Basophils, Eosinophils, Neutrophils
e) none of the above
Correct!!!
Which of the following have phagocytic ability:
a) Basophils, Eosinophils, Neutrophils
b) Eosinophils, Monocytes
c) Basophils, Macrophages, Lymphocytes
d) two of the above
e) none of the above**Not sure**
I am under the impression that all granular leukocytes have phagocytic ability. However...basophils and eosinophils have very limited phagocytic ability. The main function of eosinophils is the secretion of destructive enzymes and basophils will produce hitamines/prostaglandins.
Interferons are commonly produced by cells following a viral invasion. Which of the following statements concerning interferons is false:
a) They can attract phagocytes
b) They are viral specific
c) They are host specific
d) Interferons come in three types; alpha, beta, gama
e) Two of the above
If I recall correctly...A, C, D are true. However...interferons are not viral specific...but rather host. For example...a human interferon will have no effect on a mouse. Interferons are rather generic and apply to a wide variety of viruses. Someone correct me if I'm wrong.
Which of the following gives the order of leukocytes; starting from most abundant to least abundant?
a) Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils
b) Lymphocytes, Neutrophils, Monocytes, Eosinophils, Basophils
c) Neutrophils, Monocytes, Eosinophils, Basophis, Lymphocytes
d) Lymphocytes, Neutrophils, Eosinophils, Basophils, Monocytes
e) Neutrophils, Monocytes, Basophils, Eosinophils, Lymphocytes
Correct!!!! Never Let Monkeys Eat Bannanas!!!!
