Aman feels anxious and frightened because he senses that someone is following him home. once he safely reaches home and locks the door, his heart and respiratory rate slow. which parts of the nervous system were activated during these events, and in which order? sympathetic; parasympathetic parasympathetic; sympathetic sensory somatic; autonomic autonomic; sensory somatic

The correct answer is Sympathetic and Parasympathetic nervous system.

Explanation:

The autonomous nervous system is conformed by the sympathetic nervous system and the parasympathetic nervous system.

The body’s stress response is mediated by the sympathetic nervous system (SNS), and the hypothalamic-pituitary-adrenal (HPA) system. The sympathetic nervous system prepares the body for stressful situations that require an alert state or strength. It is responsible for the neural fight-or-flight response to stress.

In a stressful situation the hypothalamus, which is in charge of the stress response, sends signals to the pituitary gland and the adrenal medulla. The adrenal medulla secretes the neurotransmitters and hormones adrenaline and noradrenalin to the bloodstream. These hormones get the body ready for a response to stress, by increasing heart biting frequency and strength, increasing blood pressure, stimulating respiration, and dilating respiratory tracts.

The parasympathetic nervous system is activated during rest and digestion, and this occurs when the threat factor is over, and the body gets back into a balanced state.

In general, parasympathetic nervous system´s actions are contrary to the sympathetic nervous system. It reduces arterial pressure, respiratory and cardiac frequency, and maintain energy through relaxation and rest.
