poaOOD Answer questions #88-91. Refer to the diagram above 88. The cells in picture C are called cardiac cells. Cardiac cells areand a) involuntary, non-striated b) voluntary, non-striated c) involuntary, striated d) voluntary, striated 89. The cells in picture D form a simple layer of epithelial cells a) true b) false 90. Letter B. These cells are_ a) columnar b) squamous c) cuboidal d) none of above 91. Letter E represents skeletal muscle. Which of the following is NOT located in picture E? a) A band b) sarcomere c) dense bodies d) troponin e) none of above Answer questions #92-96 using the diagram above 92. Letter A is pointing to dendrites that contain a) sensory receptors b) Na channels c) K channels d) all of above 93. Letter B. This specific location of the axon contains Na channels a) true b) false 94. Letter C. What type of channels are most abundant in this area? a) Na b) Ca c) Mg d) c e) all of above 95. Letter D. This portion of the neuron is called the cell body,. Which structure is located here? a) ribosomes b) neurotransmitters c) golgi complex d) all of aboveExplanation / Answer
88. c. involuntary and striated.
89. a.True [ this is a picture of stratified squamous epithelium tissue]
90. c. cuboidal [ as you can clearly see the cube-shaped cells ]
91. c. dense bodies [ dense bodies are located in smooth muscle, but the picture is of striated skeletal muscle.]
92. d. all of the above [ generation of action potential in dendrite is the same process as in axon.]
93.b. False [ in axone Na K+ and Ca++ channels are located in the node of Ranvier, not in the myelinated zone of the axon]
94. b.Ca [ axon terminal have lots of Ca channel, entry of Ca into axon terminal causes synaptic vesicles to release acetyl choline]
95. d. all of above [ ribosomes = nissl body, neurotransmitters are made in the cell body then transported to axonal end, ]
