The Nervous + Endocrine System

• The human nervous system is divided into the Central Nervous System and the Peripheral Nervous System.
• The Central Nervous System is made up of the brain and spinal cord.
• The Peripheral Nervous System is made up of the autonomic nervous system and the somatic nervous system.
• The autonomic nervous system is further split into sympathetic and parasympathetic nervous system.
• The endocrine system consists of a number of glands that send chemical messages called hormones throughout the blood stream.
• During stress, the endocrine system and sympathetic branch of the ANS work together to produce the fight or flight response.
• The nervous system is a specialised network of cells which work as a communication system. It collects and responds to information in the environment.
• The nervous system co-ordinates the working of different organs and cells.
• The brain provides conscious awareness and is split up into two hemispheres
• The outer layer of the brain is called the cerebral cortex which is only found in mammals and is highly developed in humans.
