Taste buds on the surface of the tongue can detect a taste only when chemicals
are dissolved in saliva so that chemoreceptors can start an impulse to the brain.
Which of the following statements is correct about the taste sensory pathway?!
A The temporal lobe of the cerebrum perceives the taste sensation
B. The tip of the tongue senses sweet, and the periphery senses sour and
salty flavours
C Taste buds sense taste, and the parietal lobe perceives taste.
D. Nerve impulses trigger taste buds and send information to the brain.

Creation of an unnaturally uniform sample to represent a diverse populationcan be avoided by: a. including only willing b. asking another scientist for .c. choosing only identical participants. d. selecting individuals at random.

What is the cause hearing loss in human being

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
