The Brain Development and Structure Flashcards
What are the 3 primary sections of the anterior end of the embryonic central nervous system
Prosencephalon
Mesencephalon
Rhombencephalon
What does the Prosencephalon give rise to
Telencephalon, diencephalon and basal ganglia
What does the Mesencephalon give rise to
the midbrain
What does the rhombencephalon give rise to
the pons, cerebellum, and medulla oblongata
What areas of the vertebrate brain are in the telencephalon
cerebral cortex, forebrain structures, basal ganglia, and olfactory system
What areas of the vertebrate brain are in the diencephalon
thalamus, hypothalamus, subthalamus, and epithalamus
What areas of the vertebrate brain are in the metencephalon
pons and cerebellum
What areas of the vertebrate brain are in the myelencephalon
medulla oblongata
In terms of brain development among vertebrates, what is the overall phylogenetic trend & what factors have contributed to this trend
Increased connections between the thalamus and telencephalon
What are the major functions of the medulla
control vital processes like heartbeat, breathing, and blood pressure
What are the major functions of the pons
Transmit signals between the forebrain and the cerebellum
What are the major functions of the cerebellum
Coordinating voluntary movements
What are the major functions of the tectum
eye movement
What are the functions of the epiphysis (pineal gland)
receive and convey info about the light/ dark cycle (produce melatonin)
What are the functions of the hypothalamus
homeostasis ( thermoregulation, reproduction, thirst, body weight, hunger and more)
