Final answer:
The axons of neurosecretory neurons form connections with the posterior pituitary gland, where they store and secrete hormones directly into the bloodstream.
Step-by-step explanation:
The axons of the neurosecretory neurons extend through the infundibulum and form connections with the posterior pituitary gland. These neurons do not form typical synaptic connections; instead, they store and secrete hormones directly into the bloodstream. The hormones produced by the hypothalamus, such as oxytocin and antidiuretic hormone (ADH), travel along these axons and are stored in the axon terminals within the posterior pituitary. When the hypothalamus sends a signal, these hormones are released from the axon terminals into the bloodstream.
