Question
The region of the brain that provides your individual personality character traits is the ___ a. Parietal lobe b. Ethmoid lobe c. Frontal lobe d. Temporal lobe e. occipital lobe Which of the following organs/tissues receive their PSNS innervation from the vagus nerve (CN X)? 1. Heart (SA & AV nodes) 2. Urinary bladder 3. Gall Bladder 4. Gastric pits in stomach 5. Erectile tissue (Penis Clitoris) 6. Lacrimal glands a. 1, 2, 6 b. 1, 3, 4 c. 2, 3, 5, 6 d. 1, 3, 4, 6 e. 1, 2, 3, 4, 5, 6 Place the following events in the correct chronological sequence as they would occur during your sense of Vision (seeing an object.). 1. Photons of light enter the eyeball by passing through the cornea & the pupil. 2. PDE cleaves cGMP to GMP thereby closing cGMP-gated cation channel - hyperpolarizing 3. Light rays are refracted by the lens of the eye onto the retina as an inverted image of the original. 4. IPSP causing neurotransmitter no longer released onto Bipolar cell which now can depolarize. 5. Photons strike 11-cis retinal and cause it to isomerize into All-trans retinal, activating Opsin. 6. Bipolar neuron neurotransmitter causes EPSP in Ganglion cell. 7. Opsin activates transducin (G protein) which activates Phosphodiesterase (PDE) enzymes in photoreceptor disc membranes. 8. Ganglion cell reaches threshold and "fires" action potentials that propagate along optic Nerve through optic tracts & radiations back to the Visual Cortex of Occipital lobe for interpretation. a. 1, 3, 7, 2, 5, 8, 6, 4 b. 1, 2, 3, 4, 5, 6, 7, 8 c. 1, 3, 5, 7, 2, 4, 6, 8 d. 8, 6, 4, 2, 7, 5, 3, 1 e. 1, 2, 6, 3, 4, 7, 6, 8 Which cranial Nerves are the "cranio-" part of the Parasympathetic Nervous system (craniosacral)? 1. Oculomotor nerve 2. Glossopharyngeal nerve 3. CN VIII 4. Facial nerve 5. CN IV 6. Vagus nerve a. 1, 2, 3 b. 2, 4, 5, 6 c. 2, 3, 5 d. 1, 2, 4, 6 e. 1, 2, 3, 4, 5, 6Explanation / Answer
Answer:
68) c.
Expaination: The region of the brain that provide your individual pesonality /character trait is Frontal lobe. The brain is divided into 4 lobes i.e. frontal, parietal, occipital, and temporal. Among all, the reseach proved that the Frontal lobe is the region of the brain provides individual pesonality /character traits (that are Openness, extraversion, agreeableness, conscientiousness and neuroticism).
69) b.
Expaination: The parasympathetic nervous system (PSNS) is one division of 3 kinds of autonomic nervous system. The function of autonomic nervous system is to regulate the unconscious actions of the body. The nerve fibres of PSNS arise from the central nervous system and include several cranial nerves (which emerge directly from the brain). The more specefic are the facial nerve, oculomotor nerve, glossopharyngeal nerve, and vagus nerve.
The vagus nurve is the tenth cranial nerve so called as CN X and it is the longest nurve of the autonomic nervous system. The organs interfaces with parasympathetic control from CN X are: heart, lungs and digestive tract. Thus, from the given options in the question, the 1.Heart, 3.gallbladder and 4. gastric pits in stomach receive their PSNS innervation from the vagus nurve CN X.
70) c.
The given events in correct chronological sequence as they would occur during your sense of vision are:
1. Photons of light enter the eyeball by passing through the cornea & the pupil
3. Light rays are refracted by the lens of the eye onto the retina as inverted image of the original
5. Photons strike 11 sex retinal and cause it to immerse into All-trans retinal, activating Opsin
7. Opsin activates transducin (G protein) which activates Phosphodiesterase (PDE) enzymes in photoreceptor disc membranes
2. PDE cleaves cGMP to GMP thereby closing cGMP-gated cation channels - hyper-polarizing the photoreceptor cell
4. IPSP causing neurotransmitters no longer released onto Bipolar cell which now can depolarize
6. Bipolar neuron transmitter causes ESPS in Ganglion cell
8. Ganglion cells reach threshold and "fires" action potentials that propagate along Optic Nerve through Optic tracts & radiations back to the Visual Cortex of Occipital lobe for interpretation
71) d.
Explaination: In human the 12 pairs of functional cranial nerves emerges directly from the brain. The nerve fibres of parasympathetic nervous system (PSNS) arise from the central nervous system and include several cranial nerves. The more specefic are the oculomotor nerve (CN III), facial nerve (CN VII), glossopharyngeal nerve (CN IX), and vagus nerve (CN X). Thus, the cranial nerves that are the "cranio" part of the parasympathetic nervous system are option 1. oculomotor nerve , 2. glossopharyngeal nerve, 4. facial nerve and 6.vagus nerve as given in the question.
