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
