Answer #1

Answer- Mitral cells send axons from the olfactory bulb to the thalamus.

The olfactory bulbs contains the axons from the olfactory receptors neurons as a source for the sensory input and mitral cells as an output.Mitral cells send axons from the olfactory bulb to the hypothalamus.Olfactory receptors are located on the cilia of olfactory neurons and the synapse of the sensory olfactory neurons.Olfactory receptors activate G-proteins and facilitate the activation of the adenylate cyclase III which causes the increase in intracellular cAMP concentration.The granule cells present in the olfactory neurons synapse with the dendrites of the mitral cells to form the local lateral inhibitory signal.

Which of the following statements about brain injury is FALSE? Chronic traumatic encephalopathy (CTE) is caused by repeated brain trauma including those that are subconcussive. A seizure is a transient event characterized by synchrony in the discharge of the involved neurons. Epidural stimulation is used to bring spinal neurons below (caudal to) a spinal cord injury close to threshold so that weak voluntary input from the motor cortex can bring those neurons to threshold resulting in movement. Central axons normally...

Which of the following statements regarding regulation of body functions and systems is false? Both the nervous system and endocrine system use chemicals to send messages. The nervous system and endocrine system cause opposite effects in the same effectors. The nervous system regulates only somatic function, while the endocrine system only affects autonomic structures. For the nervous and endocrine systems to function, the receiving cells must have the correct type of receptors.

Which of following statements about learning and memory is FALSE? Memory is all or none: either memories of all types are completely intact or completely lost. In Pavlovian conditioning the development of the conditioned response requires pairing of the conditioned stimulus and the unconditioned stimulus. Place cells are located in the hippocampus. Long term potentiation involves a growth of dendritic spines in the postsynaptic cell.
