of an individual‚ but also their biology. The Biological foundation of Psychology involves the electrical and chemical processes in the nervous system that cause us to feel‚ have fears‚ and develop thoughts. There are many biological factors that can influence psychological functioning. From the neuron to the different parts of the nervous system‚ each can impact mental processes and behavior. Genetics and evolution can also influence psychological functioning. Genetics and evolution

The vagus nerve is part of the autonomic nervous system‚ has efferent fibers‚ ascending signals from the brain to the peripheral organs‚ as well as afferent sensory fibers‚ and transmits information from the peripheral tissue to the brain. The ANS consists of three components: the sympathetic‚ noradrenergic and parasympathetic‚ cholinergic systems that occur in the CNS‚ with the cell body in the brainstem and spinal cord and ENS 68.

HYPONATRAEMIA IN THE NEUROSURGICAL PATIENT INTRODUCTION Sodium the most abundant electrolyte in the human body‚ and therefore the osmolality of body fluids is strongly dependent on its concentration. Osmolality in turn is important in maintaining homeostasis within the brain. Ironically‚ dysfunction of the brain can cause changes in sodium homeostasis. To avoid neurological deterioration‚ morbidity or mortality the sodium level must be corrected promptly. The two most common causes of hyponatraemia

Measurement of Heart Rate for Autonomic Nervous System Abstract: The Autonomic Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger

Nervous System II: Anatomy Review 1. The somatic nervous system stimulates ____________ muscle. The autonomic nervous system stimulates ___________ muscle‚ ____________ muscle‚ and ___________. 2. The autonomic nervous system (ANS) consists of two divisions‚ each innervating the effector organs. The sympathetic nervous system (SNS) generally speeds up everything except digestion. The parasympathetic nervous system (PNS) generally slows down everything but digestion.

Central Nervous System Stimulants Types Stimulants can range from mild legal forms like caffeine to severe illegal drugs like methamphetamines. Each type has different effects at different levels and all can be lethal if taken in excessive quantities. The first type is the cocaine family which consists of cocaine HCL‚ cocaine freebase or crack‚ and cocaine paste.
