Give the Answers

1. What do you mean by the central nervous system?  Show in a diagram the main parts of the central nervous system 

Ans: Man is a psycho – physical organism. The source of mind is the body. Mental processes and bodily activities are like two rails running parallel to each other. The central nervous system integrates our body into one unit. The central nervous system is formed by the brain and the spinal cord. 

2. Show how the eyes are related to the central nervous system. 

Ans: The eye is the receptor of sight through the eyes a person experiences light, color, shape and size. The structure of the eye is similar to that of the camera. The eye is stimulated by light. When light falls on an object, the retina is stimulated and this sensation is carried to the brain by the optic nerve. Through the cooperation of the eye, nerves and brain. 

We see “The different parts of the eye are cornea, aqueous humour, iris, pupil, lens, ciliary muscles, vitreous humour, saluretic coat, choroid, retina, optic nerve, yellow spot and blind spot. 

3. State the importance of receptions and effected. 

Ans: The organs which help us to receive information about the external world are known as “Receptors or sense organs. They are also known as the gateway of knowledge. The receptors are of five types. Eyes for sight, ears for hearing, nose for smell, skin for touch and tongue for taste. Each sense organs cannot carry out the function of another receptors help in notification and discrimination of similar as well as dissimilar experiences. 

For example, an elephant seen for the first time by an individual is a new experience but when it is seen the second time it is identified by the eyes. This is the same with all the other sense organs.

Effectors : Effectors are those parts of the body through which the behaviour of a person is completed. The effectors work after the body receives some kind of sensation. For example if a person sees a snake, he will somehow try to escape from it. This action is produced by the effectors. 

4. Distinguish between illusion and hallucination. 

Ans: (1) The object which creates illusion is present to sense. Hallucinations is created without the presence of any object. 

(2) The brain’s functions normally when illusion appears. 

On the other hand the brain functions abnormally in hallucinative 

(3) In illusion the behaviour, movement and other things remain normal. But in hallucinations, the behaviour, manner and movement etc. turn abnormal. 

(4) In illusion this exponent is common to everyone

On the other hand in hallucinations this experience is uncommon. 

(5) In illusion, it’s influence is deep and extensive. 

But in hallucinations it’s influence is temporary only. 

5. Explain the meaning of perception and justify the need of sense training into the education of the children. 

Ans: Perception is sensations plus meaning. It is an act of giving meaning to sensory experience. In case of perception the mind remains in an active state According to Ryburn. The process of interpretation of sensation according to experience is known as perception. It depends on our past experiences. Sensations is awareness of objects and perception is the awareness of this or that object. 

For example we hear a sound. It is sensations Then it could be obtained because we have past experiences of hearing the sound of buzzing bees. This is perception. 

Training in this sense is very essential for effective learning. It is very much essential for children who have some defect in their sense organs. Such children have to be separated from the normal ones. They need special care and training. Madame Montessori has emphasized on sense training. Sense training of the mind, of its ability to discriminate and interpret whatever the sense organs perceive. 

Sense training also provides the children with a wider sensory experience of the world. Children can gather real life experience which they otherwise do not have in their day to day life. Mere reading of books cannot achieve anything without actual sensory experience. Teachers curd parents should therefore take children out as often as possible. School journeys and excursions will provide a concrete background for instruction and also help children to develop an interest in the outside world.

6. What is conception? Write five characteristics of conceptions? 

Ans: Conception is the final stage of the knowing process. Knowledge of a particular thing is complete when we form the concept of the object in our minds. It is the name given to a class of objects depending on their common qualities. It is defined as a classification of stimuli that has common characteristics. A concept is thus a system of meaning. 

It is the power to generalize objects. Perception refers to the meaning of an object while conception is naming of a class of objects on the basis of their qualities. It is therefore a much higher mental function that involves observation analysis observation, analysis abstraction, synthesis, comparison and naming of the perceptual experience. For example when we talk of birds the qualities of birds automatically comes to our mind be it a crow, cuckoo, mainah, sparrow etc.

Characteristics :

(1) Conception is a mental activity through which perceptual experiences are mixed with the previous perceptions. 

(2) It is an act of naming a class for objects on the basis of their common qualities. 

(3) Concept is a generalised idea about the things, person or events. It is not related to a particular object, individual or event. It stands for general class. 

(4) Conception is based on perception and not on sensations. 

(5) It may be concrete or abstract as well as objective or subjective. 

7. What are the effectors and what are their functions? 

Ans: The receptor organs of the body receive the stimuli of the environment and send their impulses to the brain. The brain reacts to them by sending the message to the respective organ of the body. The organs through which the responses find expression are known as the effectors. 

Following are the function of effectors : (1) Thyroid Gland. 

(2) Parathyroid Gland. 

(3) The Adrenal Gland. 

(4) The Pituitary Gland. 

(5) The Sex Gland or Gonads.
