Nervous System Concept Map

The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body, coordinating voluntary and involuntary actions and transmitting sensory information.

The nervous system is divided into the central nervous system (CNS) and the peripheral nervous system (PNS).

The central nervous system consists of the brain and spinal cord, which process information and control most functions of the body and mind.

The peripheral nervous system connects the CNS to the limbs and organs, serving as a communication relay between the brain and the rest of the body.

The somatic nervous system is responsible for voluntary movements and the relay of sensory information to the CNS.

Reflex arcs are neural pathways that control reflex actions, involving a direct route from sensory neurons to motor neurons, bypassing the brain for quick responses.

The autonomic nervous system controls involuntary physiological functions such as heart rate, digestion, and respiratory rate, operating without conscious control.

The 'fight or flight' response is a physiological reaction to perceived threats, preparing the body to either confront or escape from danger.

Oxytocin is a hormone that plays a significant role in social bonding, childbirth, and breastfeeding, often referred to as the 'love hormone' due to its effects on promoting feelings of connection.

The 'tend and befriend' response is a behavioral pattern observed in stressful situations, particularly among females, involving nurturing activities and forming social networks for mutual support.
