Cerebellum Four lobes are: Frontal-largest lobe‚ concentration‚ abstract thought‚ information storage‚ memory and motor function‚ Broca’s area (motor control of speech)‚ affect‚ judgement‚ personality and inhibitions Parietal- sensory lobe‚ analyzes sensory information

CALLUS INDUCTION By: Sonali Pradhan‚08-11-2013 ABSTRACT The present study describes a reliable method for callus induction of Hybanthus ennaspermus‚an important medicinal plant plant. Calli were in vitro initiated from leaves segments using Murashige and Skog (1962) basal media. The effect of NAA (_-naphthalene acetic acid) and 2‚4-D (2‚4-Dichlorophenoxy acetic acid) on callus induction was investigated. It was found that growth regulators and their concentrations have obvious effects on the

-We have 2 parts in our nervous system: The central nervous system (CNS) is the nerves in our brain and spinal chord. The peripheral nervous system (PNS) is a network of nerve cells in the rest of our body. -Our nervous system detects stimuli and allows us to react to them. -Stimulus: a change‚ action or occurrence in the environment that can cause an organism to respond. Eg. Light‚ noise‚ pressure… How do we detect stimuli? -We have sensory organs that detect particular stimuli eg. Skin What

The Nervous System is the system of cells‚ tissues‚ and organs that regulates the body’s responses to internal and external stimuli. In vertebrates it consists of the brain‚ spinal cord‚ nerves‚ ganglia‚ and parts of the receptor and effector organs. Your nervous system is composed of the central nervous system‚ the cranial nerves‚ and the peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerves connect the brain to the head. The four groups of nerves

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
