aqueous humor‚ lens and vitreous humor before reaching the retina. It must then pass through the inner layers of the retina to reach the photoreceptive layer of rods and cones. 2. When the photoreceptors are stimulated they transmit impulses to the bipolar cells that project to the ganglion cells of retina. 3. The axons from the ganglion cells converge at the optic disc to form optic nerve which enters the cranial cavity through the optic foramen. At the optic disc these axons acquire a myelin coat

Chapter 12: Nervous Tissue - The nervous system includes all nervous tissue in the body -Neural tissue contains two types of cells: 1) neurons (10% of all neurons‚ conduct nerve impulses) 2) neuroglia (support neurons) -We have 100 billion neurons -Organs of the nervous system: brain‚ spinal cord‚ sensory receptors of sense organs (eyes‚ ears‚ etc.)‚ and nerves (connects the nervous system with other systems‚ bundle of neurons that relay information) -Functions of the nervous system: 1) sensory

Geopolitical importance of Pakistan Defination:The study of the relationship among politics and geography‚ demography‚ and economics‚ especially with respect to the foreign policy of a nation. ‘’ The foreign policy of a country is determined by its geography’’. (Napoleon) This may be an exaggeration‚ but there can be no question that geography has had decisive effect upon civilization and upon national development.

Zuse Z3‚ ENIAC and EDSAC were some of the early digital computers. * First-generation computers were based on the von Neumann architecture. * The second generation computers were characterized by the replacement of vacuum tube by bipolar transistors. They were composed of printed circuit boards. | After 1960 | These years witnessed the development of the third generation computers. They were based on integrated circuits. Computer systems of this period had large

capacitors fabricated are usually less than 20 pf. Transistor‚ diodes and resistors are also fabricated on the same chip. Differential Amplifiers: Differential amplifier is a basic building block of an op-amp. The function of a differential amplifier is to amplify the difference between two input signals. How the differential amplifier is developed? Let us consider two emitter-biased circuits as shown in fig. 1. Fig. 1 The two transistors Q1 and Q2 have identical characteristics. The resistances
