PSY 263 EXAM 1
Substance p
- transmission of pain
- CGRP
Endorphins and enkephalins
- block pain
-produce pleasure (heroin, morphine)
- placebo, acupuncture effects
2 peptides
- 1.Endorphins/Enkaphalins
- 2. Substance P
Development of the nervous system
-fertilized egg divides, becomes a blob of cells
-blob of cells becomes a disk
-cells on back thicken = neural plate
-disk becomes a cylinder
-formation of neural groove, neural folds
-neural folds in the middle come together, fuse
-neural tube is formed
-neural tube closes at head and tail ends of tube
The two nervous systems within the peripheral nervous system are...
- somatic nervous system
- autonomic nervous system
, Somatic nervous system
- Afferent nerves
- Efferent nerves
Autonomic nervous systems
- Sympathetic division
- Parasympathetic division
Sympathetic division
- fight or flight
- Autonomic nervous systems
Parasympathetic division
- food and fortification (sex)
Parts of the midbrain
- Tegmentum
- tectum
- neural tube in midbrain
- cranial nerves
Tegmentum
- bottom half of the mid brain
- reticular formation
- periaqueductal gray (pain system)
- cell bodies of dopamine releasing neurons
3 bends that develop in the brain become:
- hindbrain (first to develop)
