Responses in an organism are typically carried out by the nervous system and the endocrine system. The nervous system, through neurons, transmits signals that lead to immediate reactions, while the endocrine system releases hormones for longer-lasting effects. Together, they coordinate the organism's response to stimuli, ensuring appropriate actions are taken based on internal and external conditions.
The nerve net of a cnidarian carries sensory information and coordinates movement and responses to stimuli. This decentralized network allows for quick reactions to the environment.
The nervous system carries messages around the body through electrical and chemical signals. The brain, spinal cord, and peripheral nerves work together to transmit information and coordinate responses to various stimuli.
Effectors that bring about change receive information from the efferent pathway of a feedback system. This pathway carries signals from the control center to the effector in response to the input received from the afferent pathway. The effector then carries out the necessary responses to maintain homeostasis in the body.
Yes, the peripheral nervous system (PNS) is involved in reflex actions. Reflex arcs allow sensory information to be processed in the spinal cord and produce motor responses without involving the brain. The PNS carries the sensory information to the spinal cord and the motor responses back to the muscles or glands.
