The nervous system: structure and function of neurones, the central nervous system, the brain (cerebral hemispheres, cerebellum, hypothalamus, pituitary), reflex arcs, sensory receptors, synapses. The hormonal system: pituitary, thyroid, adrenal, pancreas, gonads. Sense organs (eye, ear). Homeostasis: temperature, water balance, blood glucose. The interaction of nervous and hormonal regulation.

This strand is the heart of the therapeutic resonance argument for Human Biology in the Curriculum Rationale v2.0. For learners managing anxiety, SEMH difficulties, or disordered relationships with their bodies, content covering the nervous system, the brain, mental health, and homeostasis is not abstract — it is a structured framework for understanding their own experience. Reflection and Rest both anchor here.
