Answer:

True

Step-by-step explanation:

Autonomic nervous system has two parts, sympathetic and parasympathetic nervous system. They function involuntarily to regulate body functions. They control the same set of body functions but work opposite to each other.

Sympathetic nervous system initiates "fight or flight" response during a threat or injury. Heart rate increases and muscles contract to take any immediate action. Since Melinda perceived the bear as threat her sympathetic nervous system was activated to deal with this emergency.

Parasympathetic nervous system relaxes the body and is responsible for "rest and digest" function. It inhibits high energy consuming body functions and blood flow is diverted to other functions like digestion. When Melinda averted the emergency, her parasympathetic nervous system brought her body back to the relaxed state.

Answer:

True

1. sympathetic nervous system

2. parasympathetic nervous system

Step-by-step explanation:

The sympathetic nervous system is responsible for preparing the body for emergency conditions. The sympathetic nervous system stimulates the release of stress hormones from the adrenal medulla to bring about fight or flight responses. It includes dilation of the pupil, increased heart rate and blood pressure, and increased force of contraction of heart, etc. Altogether, these physiological responses prepare the body for stress conditions.

On the other hand, the parasympathetic nervous system is responsible for rest and digest activities to restore the energy of the body during the recovery period. It stimulates the activities of the digestive glands and gastrointestinal tract to increased digestion and absorption of energy supplying nutrients.
