The use of corporate messaging has generated tremendous success in HCL Technologies (HCLT) transformational journey‚ championed by Vineet Nayar‚ CEO of HCLT. Institutional and organizational change calls for the caliber of management skills and leadership prowess that Nayar provided. The organizational culture of HCLT has been altered into a collaborative‚ engaging‚ perpetual learning environment through the use of many different internal and external messaging tools.

functions of the endocrine system and its interaction with the nervous system. NEURAL COMMUNICATION • Neuron consists of a cell body and branching fibers: The dendrites receive information from sensory receptors or other neurons‚ and the axons pass that information along to other neurons. A layer of fatty cells‚ called the myelin sheath *‚ insulates the fibers of some neurons and helps speed their impulses. • A neural impulse fires when the neuron is stimulated by pressure‚ heat

The Ionic mechanism and propagation of action potentials. The action potential is the result of a large‚ sudden increase in sodium permeability of the membrane. The resulting rush of sodium ions into the membrane and accumulation of positive charge on its inner surface drives the potential towards Ena. This is followed by repolarisation‚ whereby there is a large increase in the membranes permeability to potassium ions‚ hence the membrane returns to Ek. Explanation of the (ionic) mechanisms underlying

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)

Dendrites – bushy fibers which extend from the soma; receives impulses and directs them towards soma Axon – an extension of the neuron from the soma which ends in branching terminal fibers (or synaptic/axon terminals) Myelin Sheath – a layer of segmented fatty tissue which encases the axon‚ enabling impulses to be fired much faster as it hops from node to node.
