Neuroanatomy Flashcards
Unit 1: Chapter 3
Frontal Lobe
- Motor Function (pre central gyrus, motor homunculus)
- Language production (Broca’s area)
- Attention
-Planning; Impulse Control
Parietal Lobe
- Somatic Sensory processing (Postcentral gyrus, sensory homunculus)
-Sensory integration (Angular gyrus) - Spatial skills
-Attention
Temporal Lobe
- Audition
(Wernicke’s aphasia) - Memory
- Facial Recognition
(Fusiform face area FFA)
Occipital Lobe
-Vision
-Visual Consciousness
Forebrain
- Basal ganglia
- Limbi system
3.Thalamus - Hypothalamus
Midbrain
1.Sup/inf colliculi
2. Brain stem (also in the Hindbrain)
Hindbrain
- Cerebellum
- Reticular Formation
- Pons
4.Medulla - Brain Stem (reticular formation)–> (also in Midbrain)
Basal Ganglia
- includes caudate, putamen and globus pallidus
(Nuc.Accumbens=ventral striatum)
-are important in selecting movements - reward learning
Limbic system
Includes amygdala, hippocampus, cingulate cortex, hypothalamus, others
-emotional expression (amygdala and fear)
Thalamus and hypothalamus
The thalamus
- sensory relay
- controls information flow into the cortex
The hypothalamus
- regulates bodily functions (homeostasis)
- In charge of fighting, fleeing, feeding, and fornication (4 F’s)
Midbrain contains
Tectum
- holds the superior and inferior colliculi
Tegmentum
- periaqueductal gray
- red nucleus
-substantia nigra
What are neurons
-cells in the nervous system
- communicate with one another
- information-processing tasks
What are axons
Axons are a long and slender path covered in myelin sheath to allow neural signals to travel quickly.
The ends of axons have terminal buttons that contain synaptic vesicles (storage sites for Neurotransmitters)
Macroglia
The immune cells of the CNS.
- Astrocytes
- Oligodendrocytes
- Schwann Cells
Oligodendrocytes (CNS) and Schwann Cells (PNS) myelinate neurons
