During the alarm stage of the general adaptation syndrome, . the central and somatic systems are activated synaptic activity and the somatic nervous system activate to send messages from the CNS to muscles the sympathetic nervous system is activated and adrenal glands release hormones neurotransmitter levels and the central nervous system are activated

The correct answer is ''the sympathetic nervous system is activated and adrenal glands release hormones''

Explanation:

The general adaptation syndrome is a theory based on the observation of human behavior in various stress situations and the generalized and the nonspecific activation response that affects the whole organism, which appears in any stress situation. The body responds to imminent danger in three stages: alarm, resistance and exhaustion. At the physiological level, in the alarm stage two systems are activated: the neural and the neuroendocrine. This phase appears immediately after the threat. Different hormones are released: adrenaline, corticotropin and corticosteroids, to improve our performance temporarily.
