Understanding Biopsychology 🧠

The fight or flight response is the body’s natural physiological reaction to stressful, frightening, or dangerous events. It is activated by the perception of threat, quickly igniting the sympathetic nervous system and releasing hormones, preparing the body to face a threat or run to safety.

The central nervous system (CNS) consists of the brain and the spinal cord. It acts as the body’s control center, processing sensory information and directing responses.

The autonomic nervous system (ANS) is a nervous system component responsible for regulating involuntary bodily functions, such as heart rate, digestion, respiratory rate, and pupillary response.

The HPA axis, or hypothalamic-pituitary-adrenal axis, is a complex set of interactions between the hypothalamus, pituitary gland, and adrenal glands.

The peripheral nervous system (PNS) is critical for connecting the central nervous system (CNS) to the rest of the body. It is essential for bodily functions such as movement, sensation, and autonomic processes.
