Question

name zaiyna w nervous system directions: with a partner/small group, read the following scenarios and identify the part of the nervous system being used or activated: 1. during a culinary class, a student accidentally touches a hot stove while reaching for a knife. what type of neurons are involved in the immediate withdrawal of the hand from the hot surface, and what is this pathway called? 2. a student has been feeling extremely tired, has trouble concentrating, and often feels depressed. after visiting a doctor, they are diagnosed with an undersupply of a particular neurotransmitter. which neurotransmitter is likely undersupplied, leading to these symptoms, and what role does it play in the nervous system? 3. while walking home at night, a student hears a sudden, loud noise behind them. their heart rate increases, and they feel a surge of energy, ready to either run or defend themselves. which part of the nervous system is activated in this situation, and what is the primary hormone involved in this response? 4. a student is playing basketball and catches the ball. they then dribble it and pass it to a teammate. which neurons are responsible for feeling the ball in their hands and then coordinating the movement to dribble and pass? 5. a student is studying for an exam and uses different strategies to memorize the information, such as making flashcards and visualizing concepts. which part of the brain is primarily responsible for memory formation and spatial navigation? 6. a student touches a cold metal surface and immediately feels the cold sensation, followed by the decision to move their hand away. describe the process of neural transmission from the moment the student touches the cold surface to the moment they move their hand away.

Explanation:

1. Sensory and motor neurons are involved in the hand - withdrawal reflex. This is a spinal reflex pathway.
2. Serotonin is likely the undersupplied neurotransmitter. It regulates mood, sleep, and appetite in the nervous system.
3. The sympathetic nervous system is activated. The primary hormone is adrenaline (epinephrine), which prepares the body for a "fight - or - flight" response.
4. Sensory neurons detect the ball, and motor neurons coordinate the dribbling and passing movements.
5. The hippocampus is primarily responsible for memory formation and spatial navigation.
6. Sensory receptors in the skin detect the cold. The signal travels via sensory neurons to the spinal cord and then to the brain. The brain processes the information and sends a signal via motor neurons to move the hand away.

Answer:

1. Sensory and motor neurons; spinal reflex pathway
2. Serotonin; regulates mood, sleep, and appetite
3. Sympathetic nervous system; adrenaline (epinephrine)
4. Sensory neurons and motor neurons
5. Hippocampus
6. Sensory receptors detect cold, signal travels via sensory neurons to spinal cord and brain, brain sends signal via motor neurons to move hand away
