The nervous system controls the body's reactions to outside stimuli and internal changes by sending electrical signals through neurons. These signals help coordinate actions like movement, sensation, and organ function.
The spinal cord and brain serve as intermediaries between the nervous system and internal and external environments. They receive and process sensory information from the environment, transmit signals to the body to produce responses, and regulate bodily functions to maintain homeostasis.
The characteristic of an organism to regulate its internal conditions
Organisms that do not regulate their internal conditions are called poikilotherms. They rely on external sources to maintain their body temperature, such as by moving to warmer or cooler areas. Examples include reptiles, amphibians, and many invertebrates.
Cytokines are proteins that act as messengers in the immune system, helping to regulate and coordinate the body's response to infections and other challenges. They can stimulate or suppress immune responses by signaling to different immune cells. This helps to maintain a balanced and effective immune response, preventing overreactions or inadequate responses to threats.
The endocrine system uses hormones to regulate physiological functions such as metabolism and growth, helping maintain balance in the body. The nervous system transmits signals between different parts of the body to coordinate responses to internal and external stimuli, contributing to homeostasis by adjusting body functions as needed.
The spinal cord and brain serve as intermediaries between the nervous system and internal and external environments. They receive and process sensory information from the environment, transmit signals to the body to produce responses, and regulate bodily functions to maintain homeostasis.
Both hormones and secretions of the nervous system are chemical messengers that help regulate various bodily functions. Hormones are produced by glands and released into the bloodstream to target distant organs, while nervous system secretions like neurotransmitters act locally at synapses to transmit signals between neurons. Both systems work together to maintain homeostasis and coordinate responses to internal and external stimuli.

The characteristic of an organism to regulate its internal conditions
Living things have mechanisms, such as homeostasis, to regulate their internal environment to match conditions in the external environment. This helps them ensure optimal functioning and survival in changing surroundings.
It is a document that is created for the sole purpose of controlling a comapnies external activities. The document is created by the internal management.
Yes, circadian rhythms are influenced by changes in the external light environment. Light acts as a key synchronizer of the body's internal clock, helping to regulate processes such as sleep-wake cycles, hormone release, and body temperature. Disruption of this synchronization can lead to circadian rhythm disorders.

The nervous system is responsible for transmitting information throughout the body and coordinating responses to external and internal stimuli, similar to the role of the endocrine system. Both systems help regulate and maintain the body's overall function and homeostasis.
Homeostasis works as a negative feedback mechanism, which is a kind of reflex action. When the body detects changes in external/internal environment, the receptor will generate a nerve impulse to the coordination centre and then make a response through effector. This is a reflex arc.
