Nervous, excretory, Endocrine Flashcards
The somatic nervous system controls
Voluntary actions, such as turning a television on
The endocrine system acts on the body through chemical products called
Hormones
A cell that carries information through your nervous system is a
Neuron
Tiny filtering structures where urine is produced in the kidneys are called
Nephrons
What function do the kidneys perform
Remove urea and excess water
An automatic response of the body that occurs very rapidly and without conscious control is called
A reflex
What part of the brain controls memory
Cerebrum
What is the main function of the excretory system
To collect and remove waste from the body
A motor neuron sends an impulse to
A muscle or gland
The chemical product of an endocrine gland is called

True
True or false? Urine passes out of the body through a tube called the ureter
False, urethra
True or false? The peripheral nervous system is composed of the brain and the spinal cord
False, Central
True or false? An axon carries impulses toward the nerve cell body
False, dendrite
True or false? Voluntary actions are controlled by the autonomic nervous system
False, somatic
The thick column of nervous tissue that links the brain to most of the nerves in the peripheral nervous system is the
Spinal cord
