Biology Coordination and Response Part 1

Which of the following correctly describes a sensory neurone?

• nerve cell responsible in transmitting nerve impulse from CNS to PNS

• nerve cell responsible in transducing nerve impulse from effector to CNS

• nerve cell responsible in transmitting nerve impulse from the receptor to the CNS

• nerve cell found within the CNS

Name the tissue which wraps around the dendron of a neurone, which causes faster conduction of nerve impulse

Name the neurone which is responsible in transmitting nerve impulse from the spinal cord to muscle?

which of the following is not a characteristic feature of sensory neurone?

• has a long dendron but a short axon

• cell body is irregularly shaped

• cell body is round

• transmit nerve impulse from the receptor to the CNS

What organ is responsible in receiving and transducing the stimuli from the surrounding?

Which of the following correctly shows the pathway of nerve impulse through the nervous system?

• receptor--motor neurone--sensory neurone--relay neurone--effector

• receptor--sensory neurone--motor neurone--effector

• receptor--sensory neurone--relay neurone--motor neurone--effector

• receptor--effector--sensory neurone--motor neurone

which of the following are the components of the peripheral nervous system?

• brain and cranial nerves

• brain and spinal cord

• cranial nerves and spinal nerves

• spinal cord and cranial nerves

Which structure describes the tough, inelastic membrane that forms the outermost layer of nerve fibre?

• myelin sheath

• neurilemma

• node of ranvier

• neuromuscular junction

What is a synapse?

• junction between myelin sheaths

• junction between node of ranvier

• junction between cell bodies

• junction between two neurones

What is the name of the chemical present in synapse?
