Summary
The tuberoinfundibular pathway is a dopaminergic pathway that projects from the hypothalamus to the anterior pituitary gland. Dopamine signaling in this pathway works to suppress prolactin production.
Key Points
- Tuberoinfundibular Pathway
- Dopaminergic Pathway
- Connect the tuberal region of hypothalamus (arcuate/infundibular nucleus) to the median eminence of anterior pituitary gland
- Function
- Inhibits prolactin release
- D2 signaling at lactotrophs of anterior pituitary gland inhibits PRL production and release
- Inhibits prolactin release
- Lesions
- Inhibited in Hyperprolactinemia
- Presents with decreased libido, sexual dysfunction, gynecomastia, galactorrhea
- Inhibited in Hyperprolactinemia
- Dopaminergic Pathway
