TESTE DEIN WISSEN
In which parts can the brain be separated (forebrain, midbrain, hindbrain)?
Which ventricles are found there respectively?
Lösung anzeigen
TESTE DEIN WISSEN
  • Forebrain = prosencephalon (telencephalon with lateral ventricles + diencephalon with third ventricle)
  • Midbrain = mesencephalon (with cerebral aqueduct)
  • Hindbrain = rhombencephalon (metencephalon with fourth ventricle + myencephalon)

Lösung anzeigen
TESTE DEIN WISSEN
- produced by choroid plexus (inside the ventricles)

TESTE DEIN WISSEN
What is a spinal reflex?
Lösung anzeigen
TESTE DEIN WISSEN
It’s a reflex response that is not integrated in the brain but only in the spinal cord.

What is the reticular formation?
Lösung anzeigen
TESTE DEIN WISSEN
Nuclei in the brainstem are called reticular formation.

Lösung anzeigen
TESTE DEIN WISSEN
  • Medulla oblongata: involuntary functions (breathing, blood pressure …)
  • pons: relay station between cerebrum and cerebellum 
  • mesencephalon: control of eye movement

TESTE DEIN WISSEN
What is called the “little brain“ and what are the major functions?
Lösung anzeigen
TESTE DEIN WISSEN
Cerebellum
- motor coordination (input from motorcortex and somatic receptors)

TESTE DEIN WISSEN
Which structures belong to the diencephalon? Name each main function. 
Lösung anzeigen
TESTE DEIN WISSEN
  • thalamus: integrating center and main relay station to the cortex

TESTE DEIN WISSEN
Explain the broad overview of the nervous system.
Lösung anzeigen
TESTE DEIN WISSEN
- CNS = Brain and spinal cord

- PNS = afferent and efferent neurons 
  • afferent sensory fivers devide in somatic and visceral
  • efferent Neurons decide in somatic (skeletal muscle) and autonomic (smooth and cardiac muscle) devision
