It explores the grand themes of family, faith, and survival.
This article discusses the Easter eggs and homages in Zootopia 2 that you may have discovered. The main content includes: character and archetype Easter eggs, cinematic universe crossover Easter eggs, animal ecology and behavior references, symbol and metaphor Easter eggs, social satire and brand allusions, and emotional storylines and sequel foreshadowing.

somatosensory system
somatic sensation
peripheral afferent nerve fibers
Processing information about limb position and muscle strength
control body movements
Specialized receptors for proprioception (joints, muscles) and skin sensitivity
touch
Wenjue
pain
The fourth subtype is unknown, but is only found in hairy skin
peripheral nervous system
touch
Provides perception of pressure, vibration and texture; relies on four different receptors in the skin of the fingers
Fast adaptive receptors,
tactile corpuscle
toroidal body
slow adapting receptors,
Merkel disk
Ruffini terminals (low threshold mechanoreceptors)
Wenjue
cold receptor
thermoreceptor
pain
Not only depends on nociceptor input, the sea depends on other signal processing processes. such as emotions or situations
pleasure
CT afferent nerve fibers are the limbic tactile system, which is the material basis for social behavior between individuals, emotions, endocrine and dependent reactions (pleasant touch) during skin contact
The brain (insular cortex) is experimentally linked to the positive and negative emotional aspects of skin sensitivity
sympathetic nervous system
Sympathetic nerve fibers play a role in inducing and exacerbating severe reactions
Outgoing sympathetic fibers (preganglionic fibers)
postganglionic nerve fibers
alpha receptor
Adrenaline activation, norepinephrine activation
Receptor activation causes vasoconstriction
beta receptor
Adrenaline activation
Receptor activation causes vasodilation
Receptors and signaling pathways
Stimulus signals acting on nociceptors, such as heat, pain, or chemical stimuli, are peripherally controlled through complex regulation of a series of ion channels.
Capsaicin receptor subtype 1 (VR1, also known as TRPV1) is a typical cation channel. Expressed on the surface of cutaneous sensory nerve fibers, mast cells, and epithelial cells of skin adnexal structures.
opioids
μ-opioid receptor subtype 1A (MOR 1A) and calcitonin gene-related peptide coexist on the surface of human sensory nerve fibers, suggesting a functional relationship between opioid agonists in anti-inflammatory and analgesic aspects.
A range of cell types, including neurons, keratinocytes, and immune cells, synthesize endogenous opioids, and there are three families of opioid peptides
Promelanotropin (POMC)
proenkephalin
prodynorphin
cannabinoids
Cannabinoids can activate VR1, which may explain the associated activity of cannabinoids as vasodilators.
central projection
spinal cord
The trigeminal nerve innervates the entire facial skin structure (including the oral mucosa)
brain
The cerebral cortex is thought to have nine different areas primarily responsible for somatosensory sensations
Primary somatosensory cortex (SI)
2
1
3a
3b
Secondary somatosensory cortex (SII)
Located in the upper region of the lateral sulcus
insular cortex
posterior parietal cortex
Zone 5
Area 7b
