Nervous System Review Sheet 1. List three functions of the nervous system and give a specific example of each. • Reception of stimuli from environment (internal or external) and relay of info to CNS (Sensory division of PNS) – e.g. Receptors in your ear send a signal to the brain when the bell rings. • Integration of stimuli to decide on a response (CNS) – e.g. Your brain receives the signal that the bell is ringing‚ along with signals from your eyes that tell you it is time for class

Systems’ thinking is derived from viewing elements and components that work together in relationships for the overall good of the vision or the whole. Every aspect of our lives is involved in a system whether it is electronics‚ biology‚ organizations‚ relationships‚ or ecology. By being able to recognize these systems we can focus on facts‚ not theories‚ and can look at a problem or issue understanding better where it came from‚ why it happened‚ and how to improve it. "Systems thinking is a discipline

sensitive to specific odorant types. Each contains an olfactory receptor‚ similar to the retinal photoreceptors in the visual pathway. The olfactory receptor activates and sends a signal from the ORN to the glomeruli in the olfactory bulb‚ which receives sensory input‚ matches it to and fires for a particular odorant association. Odors leave the olfactory bulb after being mapped to the glomeruli and head to the piriform cortex‚ the main site for olfaction‚ where associations are made from learning. Chemotopic

Integumentary System Definition Integument comes from the Latin word integumentum‚ meaning "cover" or an external layer.In animals and plants integument is any natural external covering‚ such as skin and membrane. The human integumentary system is an external body covering‚ but also much more. In human beings integumentary system is one of the organ system that protects body from various kinds of damages‚ such as water excreation.

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) (3) modulators: interpret sensory information and send

The Senses The sensory system involves hearing‚ touching‚ tasting‚ smelling‚ and seeing‚ which provide data for perception. The eye is a sensory organ held by an orbit that allows vision (a detection of light in a way that provides mental images of objects) and holds photoreceptors. Photoreceptors are used to absorb light energy‚ which are bent by a transparent unit called the lens. Some photoreceptors in the eye are the rod cell and cone cell. Rod cells are used in dim light for coarse images and

"Systems thinking" involves thinking in loops rather than in straight lines. Because all parts of a system are interrelated‚ if change becomes initiated in one part of the system all parts will be impacted in a ripple effect all the way back to the original action – this is called a feedback loop. Discuss how a feedback loop would benefit a change initiative within an organization. Most systems have feedback loops‚ which enforce communication in some type of way. If an organization implements a

Body Systems Intergumentary- The integumentary system consists of the skin‚ hair‚ nails‚ glands‚ and nerves. The main function is to act as a barrier to protect the body from the outside. It also retains body fluids‚ protects against disease‚ eliminate waste products‚ and regulates the body temperature. Cardio Vascular- The cardiovascular system carries blood‚ oxygen‚ and nutrients to organs and tissues of the body. It also carries waste and carbon dioxide from these tissues for removal from

1. Systems theory and the Ecological perspective As a social worker‚ one must understand the impact of systems in the environment. The interactions between the individual and their multiple systems give social workers a visual of how to interpret their consumer ’s life. System theories is one way to try to interpret a consumer ’s life to have somewhat of a general idea of how to help solve the problems they are facing. The easiest way to view system theories are by creating

Systems Chart Jacqueline Wheaton BSHS 311/ Models of Effective Helping Systems Chart The term system means the consistent arrangement of things connected to unity or to operate as a whole (Dictionary‚ 2012). In Systems theory we will describe dynamics in a family as dyads‚ triads‚ and in homeostasis. In a system when one part of that system changes‚ the whole system changes. Within a family system viewed as a whole there are similar smaller systems
