CNS - Parts of the Brain (3)

1. Forebrain or Prosencephalon [includes telencephalon, diencephalon]

2. Midbrain or Mesencephalong [includes tectum, tegementum]

3. Hindbrain or Rhombencephalon [includes metencephalon, myelencephalon]

2

CNS - Telencephalon (4)

1. Cerebrum

2. Hippocampus

3. Basal Ganglia

4. Amygdala

3

CNS - Diencephalon (4)

1. Thalamus

2. Hypothalamus

3. Subthalamus

4. Epithalamus

 

Function: interactive site between CNS and endocrine/limbic system, where major motor and sensory tracts synapse

4

CNS - Tectum (2)

1. Superior Colliculi

2. Inferior Colliculi

5

CNS - Tegmentum (5)

1. Cerebral Aqueduct

2. Periaqueductal Gray 

3. Reticular Formation

4. Substantia Nigra

5. Red Nucleus 

6

CNS - Metencephalon (2)

1. Cerebellum

2. Pons

7

CNS - Myelencephalon

Medulla Oblongata

8

CNS - Brainstem (3)

1. Midbrain

2. Pons

3. Medulla Oblongata

9

PNS (2)

1. 12 Cranial Nerves

2. 31 Pairs of Spinal Nerves

10

PNS - Spinal Nerves (5)

1. 8 Cervical 

2. 12 Thoracic

3. 5 Lumbar

4. 5 Sacral

5. 1 Coccygeal

11

PNS - Spinal Nerve Roots

Anterior = Efferent (away from CNS), Motor

Posterior = Afferent (toward CNS), Sensory

12

Ganglia 

Clusters/Swellings of cells that give rise to peripheral/central nerve fibers

Can be snesory or autonomic

13

ANS - Neurotransmitters

Sympathetic = Norepinephrine

Parasympathetic = Acetylcholine

14

Somatic Nervous System 

Peripheral and motor nerve fibers, voluntary movement, all five senses

15

CNS - Cerebrum (2)

1. Outer surface = gray matter

2. Interior = white matter

16

CNS - Cerebrum Fissures (2)

1. Interhemispheric (medial longitudinal)

2. Sylvian (lateral): anterior separates temporal/frontal lobes, posterior separates temporal/parietal lobes

17

CNS - Cerebrum Sulci (3)

1. Central Sulcus: separates frontal/parietal lobes laterally

2. Parieto-Occipital Sulcus: separates parietal and occipital loes medially

3. Calcarine Sulcus: separates occipital lobe into superior/inferior havles

18
