14 Questions
Match the following parts of the nervous system with their descriptions:
Sensory Neurons = Carry impulses from receptors to the Central Nervous System Motor Neurons = Carry impulses from The Central Nervous System to effector organs Interneurons = Connect sensory to motor neurons in the Central Nervous System Spinal Cord = Transmits impulses to and from the brain and controls many reflex actions
Match the following brain parts with their functions:
Cerebrum = Controls thought, logic, will, intelligence, memory and activities connected with sense organs Cerebellum = Controls balance and muscular co-ordination Hypothalamus = Regulates the internal environment by monitoring osmoregulation, appetite, thirst, body temperature etc. Medulla oblongata = Links the brain to the spinal cord and regulates heart and breathing rates
Match the following reflex arc components with their descriptions:
Stimulus = The event that triggers the reflex action Sensory Neuron = Carries the impulse from the receptor to the spinal cord Motor Neuron = Carries the impulse from the spinal cord to the effector Effector = The muscle or gland that responds to the impulse
Match the following neurotransmitter-related terms with their descriptions:
Presynaptic Knob = The location where an impulse arrives and neurotransmitter vesicles move to the surface Synapse = The narrow gap that the neurotransmitter diffuses across Post-synaptic Swelling = The location where the neurotransmitter attaches to specific receptor sites Cholinesterase = The enzyme that inactivates the transmitter substance
Match the following parts of a neuron with their functions:
Dendrites = Collects impulses from other neurons of sensory cells Cell body = Control centre of the cell Myelin sheath = Insulates and protects axon as well as speeding up impulse Axon = Carries impulses away from the cell body to other neurons, muscles, or glands
Match the following components of the nervous system with their descriptions:
Central Nervous System = Consists of the brain and spinal cord Peripheral Nervous System = Consists of sensory receptors, sensory neurons, motor neurons, and end plates Neurons = Nerve cells Synapse = The space between neurons
Match the following steps of the nervous system with their descriptions:
Gather information about surroundings = First step of the nervous system Process and integrate information = Second step of the nervous system Inform parts of the body that need to be informed = Third step of the nervous system Movement of Nerve Impulse = How nerve impulses are sent or not sent
Match the following parts of a neuron with their functions:
Dendrites = Collects impulses from other neurons or sensory cells Cell body = Control centre of the cell Axon = Carries impulses away from the cell body to other neurons, muscles, or glands Schwann cells = Secretes myelin sheath
Match the following steps of the nervous system with their descriptions:
Gather information about surroundings = Step where the nervous system receives input from the environment Process and integrate information = Step where the nervous system analyzes and combines the received input Inform parts of the body that need to be informed = Step where the nervous system sends signals to effectors Movement of Nerve Impulse = Step where the nervous system transmits electrical signals
Match the following types of nerve cells with their descriptions:
Neuron = A nerve cell that is the basic building block of the nervous system Sensory neurons = Neurons that carry information from the sensory receptors to the central nervous system Motor neurons = Neurons that carry signals from the central nervous system to the muscles or glands Presynaptic knobs = Structures that increase contact with the effector
Match the following brain parts with their functions:
Cerebrum = Controls balance and muscular co-ordination Hypothalamus = Regulates the internal environment by monitoring osmoregulation, appetite, thirst, body temperature etc. Medulla oblongata = Controls thought, logic, will, intelligence, memory and activities connected with sense organs Cerebellum = Links the brain to the spinal cord
Match the following neuron types with their descriptions:
Sensory Neurons = Carry impulses from The Central Nervous System to effector organs Motor Neurons = Carry impulses from receptors e.g., sense organs to the Central Nervous System Interneurons = Connect sensory to motor neurons in the Central Nervous System Reflex Neurons = Involved in a reflex action, not involving the brain
Match the following parts of the nervous system with their descriptions:
Spinal Cord = Transmits impulses to and from the brain and controls many reflex actions Brain = The interpreting center for the senses. It stores information both in short-term and long-term memory Neurons = Specialized cells that transmit electrical and chemical signals in the body Reflex Arc = The nerve pathway involved in a reflex action
Match the following nervous system disorders with their descriptions:
Parkinson’s = Shuffling gait, limb tremors, no definitive cause Alzheimer’s = Memory loss, cognitive decline, brain cell death Multiple Sclerosis = Immune system attacks the protective sheath covering nerve fibers, causing communication problems between the brain and the rest of the body Epilepsy = Seizures, abnormal brain activity
