Hypothalamus

Afferent Connections:

  • Medial Forebrain Bundle: Continuation of the longitudinal dorsal fasciculus.
  • Solitary Tract Nucleus.
  • Fornix: From the hippocampus to the mammillary nucleus.
  • Thalamus: From the retina and cortex.

Efferent Connections:

  • Telencephalon: Amygdala and hippocampus.
  • Thalamus: Anterior nucleus.
  • Pituitary: Downstream efferent pathways (hypothalamic-spinal, hypothalamic-bulbar, hypothalamic-periaqueductal; mammillotegmental tract).

Functions of the Bones

  • Maintenance of different positions, the realization of movement and displacement.
  • Some participate in protection by forming cavities containing organs.
  • Participate in the production of blood cells.
  • They are an important reservoir of minerals for the body.

Bone Classification by Structure

Long Bones

These are bones in which length predominates over width and thickness. They participate in the support of the body and allow for its displacement. They are formed by two heads on the ends
