What is somatic sensory?

sensory input that is constantly perceived from receptors

What structures use somatic sensory?

What is visceral sensory?

sensory input that is not constantly perceived from receptors of blood vessels and internal organs

What structures use visceral sensory?

heart

What is somatic motor?

motor output that is constantly or voluntarily controlled

What is the effector of somatic motor?

What is autonomic motor?

motor output is not consciously/is involuntarily controlled

What are the effectors for an autonomic motor?

Corpus callosum function?

connects the left and right cerebral hemispheres of the brain

Pineal gland function?

receive information about light and dark from the environment and produce melatonin to regulate sleep-wake cycle
