biological structures on behaviour Flashcards
human body
The human body is a collection of systems which integrate to help us live. Some of these systems are useful in explaining the behaviour of an individual. An example is the nervous system.
the nervous system
The central nervous system - this is the brain and the spinal cord. These are vital in transferring messages to and from the environment and act as the centre from which all physiology is controlled.
The peripheral nervous system - this sends and receives information to the central nervous system. It will collect information from the environment in terms of temperature, pain, and threat.
The nervous system sends messages from one part of our bodies to another using nerve cells, known as neurons. These transmit impulses in the form of electrical signals.
the endocrine system
The endocrine system works to maintain the correct levels of hormones in the blood. This is done through the use of glands within the body, the most important of which is the pituitary gland.
The pituitary gland instructs other glands to secrete hormones when required. Biological psychologists state that the level of hormones in the system can affect the behaviour of an individual.
