Human Body
- The part of the brain which is concerned with muscular co-ordination in the body -Cerebellum
- The structure for the alteration of the shape of the lens - Ciliary body/ ciliary muscles
- The structure for the constriction of the pupil in bright light - Iris
- The nerve which transmits impulses from the eye to the brain - Optic Nerve
- The muscles in the human eye which are concerned with the following of objects at different distances - Radial and circular muscle/ ciliary muscle
- The unit of nervous system - Neuron
- The neurons which carry impulses from receptor to brain - Sensory neurons
- The neuron which transmits impulses from brain to the effector organ - Motor neurons
- The lower part of brain which contains reflex centre - Spinal Cord
- The number of spinal nerves in man- 31 pairs
- The middle coat of the eye, soft vascular and thin layer - Choroid
- The sensitive cells present in the retina - Rods and Cones
- The smallest bone in the human body - Stapes
- The longest bone in the human body - Femur
- Most important part of nervous system- Brain
- The membrane covering the brain and spinal cord - Meninges
- Response to a stimulus without the intervention of the will of an animal - Reflex Action
- The point in the centre of the retina where the rods and cones are highly concentrated -Yellow Spot
- One neuro-transmitter - Acetyl Choline
- Defect of the eye in which distant objects are not seen clearly - Myopia
- Defect of the eye in which near objects are not seen clearly - Hypermetropia
- A bony socket in which eye is well protected - Orbit
- A small opening in the centre of the Iris - Pupil
- Inner sensitive coat of the eye ball - Retina
- The organ of hearing - Ear
- The structure of the ear which helps in the balancing of the body- Semi-circular canals
- Jelly-like material filled in the space between the lens and the retina- Vitreous humour
- The fluid filled in the space between the cornea and the lens - Aqueous humour
- The structure that protects the eye-ball and maintains its shape - Sclera
- The structure that has a sensory organ called 'organ of corti' - Cochlea
- The defect of the eye caused due to the uneven curvature of the cornea - Astigmatism
- The parts of autonomous nervous system - Sympathetic and parasympathetic nervous system
- The nerves which transmit impulses from ear to the brain - Auditory Nerve
