Biological and environmental influences

The nervous system is responsible for regulating and determining someone's behavior in his or her environment. Reflex arc- a set of neurons that are responsible for receiving reflexive nerve impulses e. If you touch a hot frying pan, the neurons contained within the reflex arc will immediately react, causing you to withdraw your hand.

Neurotransmitters- chemicals utilized by neurons to communicate and transfer nerve impulses to other structures in the body e. There are excitatory neurotransmitters e.

Serotonin is a neurotransmitter that is responsible for feelings of happiness and well-being. High levels of serotonin would likely cause someone to behave happily high levels of self-care, socializing, etc. Structure and function of the peripheral nervous system PNS - consists of all outside nerve fibers that are not included within the brain or spinal cord.

The PNS functions to send nerve impulses from our limbs skin, muscles and trunk organs to the central nervous system for processing. Structure and function of the central nervous system CNS - consists of the brain and spinal cord. Its function is to receive and process nerve impulses from the PNS.

It is also responsible for thought processing and body movement. The brain Forebrain-consists of the cerebrum, thalamus, the limbic system, and hypothalamus. Responsible for abstract thinking, logic, and emotions. Midbrain- consists of the tegmentum, tectum, and cerebral peduncles.

Responsible for the production of dopamine, which regulates habituation and motivation. Also plays a role in vision and hearing. Hindbrain- consists of the cerebellum, pons, and medulla. Responsible for vital bodily functions motor control, respiratory and digestive reflexes as well as sexual arousal.

Lateralization of cortical functions- some of our bodies' functions occur predominantly by one side of the brain.

Left brain functions include: Right brain functions include: Methods used in studying the brain Imaging of brain structures e. Endorphins- released during extreme pleasure or pain, can have numbing effect on pain.

Norepinephrine- regulates alertness, learning, and long-term memory deficiency can lead to mood disorders. Serotonin- regulates mood, sleep, libido deficiency can cause anxiety and depression. Dopamine- plays a role in learning and ability to concentrate.

Acetylcholine- regulates memory, sleep, and plays a role in learning deficiency is associated with dementia Epinephrine Adrenaline - intensifies mood released during fight or flight The endocrine system Components of the endocrine system Hypothalamus- controls the actions of the endocrine system.

Adrenal gland- release adrenaline during "fight or flight" situation.If the administrator chooses to administer the entire LAP-3 in one sitting, we advise caution. The full LAP-3 will take approximately an hour and a half to complete and the results may be skewed by child boredom or lack of cooperation during such a long session.

Individual influences on behavior - MCAT Review

The Honors Program in the School of Biological Sciences provides an opportunity for outstanding majors in the School to pursue advanced work in independent research via participation in the Excellence in Biological Sciences Research Program and earn Honors in Biological Sciences upon graduation.

IB Psychology notes on The biological level of analysis: General learning outcomes - Explain how principles that define the Biological Level of Analysis may be demonstrated in research.

The study of the environment and sexual orientation is research into possible environmental influences on the development of human sexual orientation. Some researchers distinguish environmental influences from hormonal influences, [1] while others include biological influences such as prenatal hormones as part of environmental influences.
