Nervous System Divisions Flashcards
CNS - Parts of the Brain (3)
- Forebrain or Prosencephalon [includes telencephalon, diencephalon]
- Midbrain or Mesencephalong [includes tectum, tegementum]
- Hindbrain or Rhombencephalon [includes metencephalon, myelencephalon]
CNS - Telencephalon (4)
- Cerebrum
- Hippocampus
- Basal Ganglia
- Amygdala
CNS - Diencephalon (4)
- Thalamus
- Hypothalamus
- Subthalamus
- Epithalamus
Function: interactive site between CNS and endocrine/limbic system, where major motor and sensory tracts synapse
CNS - Tectum (2)
- Superior Colliculi
- Inferior Colliculi
CNS - Tegmentum (5)
- Cerebral Aqueduct
- Periaqueductal Gray
- Reticular Formation
- Substantia Nigra
- Red Nucleus
CNS - Metencephalon (2)
- Cerebellum
- Pons
CNS - Myelencephalon
Medulla Oblongata
CNS - Brainstem (3)
- Midbrain
- Pons
- Medulla Oblongata
PNS (2)
- 12 Cranial Nerves
- 31 Pairs of Spinal Nerves
PNS - Spinal Nerves (5)
- 8 Cervical
- 12 Thoracic
- 5 Lumbar
- 5 Sacral
- 1 Coccygeal
PNS - Spinal Nerve Roots
Anterior = Efferent (away from CNS), Motor
Posterior = Afferent (toward CNS), Sensory
Ganglia
Clusters/Swellings of cells that give rise to peripheral/central nerve fibers
Can be snesory or autonomic
ANS - Neurotransmitters
Sympathetic = Norepinephrine
Parasympathetic = Acetylcholine
Somatic Nervous System
Peripheral and motor nerve fibers, voluntary movement, all five senses
CNS - Cerebrum (2)
- Outer surface = gray matter
- Interior = white matter
CNS - Cerebrum Fissures (2)
- Interhemispheric (medial longitudinal)
- Sylvian (lateral): anterior separates temporal/frontal lobes, posterior separates temporal/parietal lobes
CNS - Cerebrum Sulci (3)
- Central Sulcus: separates frontal/parietal lobes laterally
- Parieto-Occipital Sulcus: separates parietal and occipital loes medially
- Calcarine Sulcus: separates occipital lobe into superior/inferior havles
CNS - Cerebrum Left Hemisphere Dominance (11)
