Unit 1- Maintaining Dynamic Equilibrium II Ch. 12 – The Nervous System (pp. 390-419) 12.1 – Structure of the Nervous System nervous system: a high-speed communication system which delivers information to and from the brain and spinal cord and all over the body. In any nervous system‚ there are 4 main components: (1) sensors: gather information from the external environment (sense organs) (2) conductors: carry information from sensors to modulators or from modulators to effectors (nerves)

The Endocrine System System Although we rarely think about them‚ the glands of the endocrine system and the hormones they release influence almost every cell‚ organ‚ and function of our bodies. The endocrine system is instrumental in regulating mood‚ growth and development‚ tissue function‚ and metabolism‚ as well as sexual function and reproductive processes. In general‚ the endocrine system is in charge of body processes that happen slowly‚ such as cell growth. Faster processes like breathing

function of the Autonomic Nervous System Introduction: The organs of our body are controlled by many systems in order to function correctly and efficiently in order to survive within the environment we live in. These include the heart‚ stomach and intestines and other vital organs and body systems. All of the systems in our body are regulated by a part of the nervous system called the autonomic nervous system (ANS). The ANS is part of the peripheral nervous system and it controls many organs

Nervous System The two types of the nervous system are the Central nervous system and the peripheral nervous system. They are responsible for integrating‚ processing‚ and coordinating Sensory data and motor commands the central nervous system‚ which interprets sensory input and carry information to maintain homeostasis. CNS can’t be regenerate because a CNS consists of the spinal cord that mean if it’s break the spinal cord is break also. The peripheral nervous system consists of the nerves

Human Endocrine System A system of glands and cells that make hormones that are released directly into the blood and travel to tissues and organs all over the body. The endocrine system controls growth‚ sexual development‚ sleep‚ hunger‚ and the way the body uses food. [pic] The human endocrine system modulates several processes of the body by the function of hormones. The endocrine system secretes hormones that control how bodily functions work. Thus‚ the human endocrine system watches

Nervous systems consists of the central nervous system (brain and spinal cord) and the peripheral nervous system (cranial and spinal nerves) Brain is divided into 3 major areas 1. Cerebrum Pairs of lobes 2. Brain stem 3. Cerebellum Four lobes are: Frontal-largest lobe‚ concentration‚ abstract thought‚ information storage‚ memory and motor function‚ Broca’s area (motor control of speech)‚ affect‚ judgement‚ personality and inhibitions Parietal- sensory lobe‚ analyzes sensory information

Hormones and the Endocrine System 26.1 Chemical and electrical signals coordinate body functions The Endocrine System is a group of interacting glands and tissues throughout the animal body that produce and secrete chemical to initiate and maintain body functions and activities. Chemical Signals -Hormones - are released into the bloodstream by endocrine cells and carried to all locations in the body Consists of all hormone secreting cells Works with the nervous system in regulating body activities

he nervous system is the communication network of the body. It consists of a complex collection of nerves and specialized cells‚ called neurons‚ that transmit messages across the different parts of the body in order for it to function and react correctly. They are known as the building blocks of the nervous system. Structurally they have long extensions that extend out from the cell body. There are two types of these extensions; dendrites‚ which are extensions of the neurons that receive signals
