_______ nervous system consists of all the _______ which connect the ________ nervous system to the __________________________ located at other parts of the body.

• Central, nerves, peripheral, receptor and effector

• Receptor and effector, central, nerves, peripheral

• Peripheral, nerves, central, receptor and effector

• Nerves, peripheral, receptor and effector, central

Function of spinal cord

• controls all voluntary actions of the body

• to transmit impulses from the sensory organ through central nervous system to the effector to respond accordingly

• controls the reflex actions

What is a neuron?

• Basic unit of the nervous system

• Receives impulse

• Carries impulses

• Transmit impulses out of the cell body

The function of the dendrite.

• Controls all activities of the neuron

• Transmits impulses towards a cell body

• Receives impulse from other neuron and transmits them to the cell body

• Insulator that prevents the leakage of impulses.

• Transmits impulses out of cell body

Which part of the neuron has the function of transmitting impulses out of cell body

• Cell body

• Dendron

• Dendrite

• Axon

• Myelin sheath

Human nervous system consists of

• Central Nervous System

• Peripheral nervous system

• Pulmonary nervous system

• Systemic nervous system

Which of the following neurons transmit nerve impulses from the receptor to the central nervous system

• Relay neurons

• Sensory neurons

• Motor neurons

• Proprioceptors

Humans feel hungry when their empty stomachs contract and glucose levels in their body drop. Both of the situations stimulate neurons that send messages to the brain which are interpreted as hunger. What body systems are involved in this process as described?

• digestive, muscular, integumentary, and respiratory

• digestive, excretory, integumentary, and skeletal

• circulatory, excretory, nervous, and skeletal

• circulatory, digestive, muscular, and nervous

The brain has 3 major sections that send and receive signals to control all the activities that keep a person functioning efficiently. Which major section controls breathing and heart beat?

• cerebellum

• cerebrum

• brain stem

• cortex
