Brain Development

Dividing the Brain into 3 parts, what are those 3 parts?

1. Forebrain

2. Midbrain

3. Hindbrain

4. Spinal Cord

Dividing even more, name the parts.

1. Forebrain (Prosencephalon)

   • Telencephalon

   • Dicencephalon

2. Midbrain (Mesencephalon)

   • Mesencephalon (midbrain)

3. Hindbrain (Rhombencephalon)

   • Metencephalon

   • Mylencephalon

In adults, what are they named?

1. Forebrain (Prosencephalon)

   • Telencephalon → Cerebrum

   • Dicencephalon → Dicencephalon

2. Midbrain (Mesencephalon)

   • Mesencephalon → Midbrain

3. Hindbrain (Rhombencephalon)

   • Metencephalon → Pons & Cerebellum

   • Myelencephalon → Medulla oblongata

Cerebrum

• Conscious thought processes, intellectual functions

• Memory storage and processing

• Conscious and subconscious regulation of skeletal muscle contractions

Diencephalon

1. Thalamus

   • Relay and processing centers for sensory information

2. Hypothalamus

   • Centers controlling emotions, autonomic functions, and hormone production

Pons

• Relays sensory information to cerebellum and thalamus

• Subconscious somatic and visceral motor centers

Medulla Oblongata

• Relays sensory information to thalamus and to other portions of the brain stem

• Autonomic centers for regulation of visceral function (cardiovascular, respiratory, and digestive system activities)

Cerebellum

• Coordinates complex somatic motor patterns

• Adjusts output of other somatic motor centers in brain and spinal cord
