The nervous and endocrine systems are the body's two control networks: one fires electrical signals at over 100 metres per second, the other drips hormones into the blood and waits. The Flip It deck Human Anatomy: Nervous & Endocrine (deck code RP2466, 79 cards) covers both in two clean halves: cards 1-40 on neurons, divisions and neurotransmitters, cards 41-79 on glands, hormones and endocrine disease.

Cards worth knowing cold

FrontBack
What cells produce myelin in the CNS?Oligodendrocytes
What cells produce myelin in the PNS?Schwann cells
GanglionCluster of neuron cell bodies in the PNS
Nucleus (in neuroanatomy)Cluster of neuron cell bodies in the CNS
Two most common neurotransmittersGlutamate (excitatory) and GABA (inhibitory)
Anterior vs posterior pituitaryAnterior produces TSH, ACTH, GH, LH, FSH; posterior stores and releases ADH and oxytocin
What cells in the pancreas produce glucagon?Alpha cells (in islets of Langerhans)
What does the parathyroid gland secrete?Parathyroid hormone (PTH), which regulates calcium
Addison's diseaseAdrenal insufficiency, low cortisol and aldosterone

What the deck covers

CNS vs PNS, neurons, glial cells, axons, synapses (electrical and chemical), action potentials, myelin, gray vs white matter, reflex arcs, afferent sensory and efferent motor neurons, somatic vs autonomic, sympathetic "fight or flight", parasympathetic "rest and digest", the enteric nervous system, 12 pairs of cranial nerves, acetylcholine, dopamine, long-term potentiation, meninges and dura mater, multiple sclerosis, diabetic neuropathy. Then the hypothalamus, pituitary, thyroid (T3/T4), parathyroid, adrenals (cortisol, adrenaline, aldosterone), pineal melatonin, pancreatic beta and alpha cells, insulin vs glucagon, gonads, tropic hormones, negative feedback, endocrine/paracrine/autocrine signaling, Type 1 diabetes, hypothyroidism, Graves', Cushing's and pituitary adenoma.

Study it in pairs

This deck is built on mirror images, so drill them as pairs rather than single cards: oligodendrocytes/Schwann cells, ganglion/nucleus, sympathetic/parasympathetic, afferent/efferent, insulin/glucagon, alpha/beta cells, Graves'/hypothyroidism, Cushing's/Addison's. When one card of a pair comes up, say the other one out loud before flipping. Most exam questions on these topics are contrast questions anyway.

Three gaps to patch yourself

  • No brain anatomy. The deck never names the cerebrum, cerebellum, brainstem, thalamus or the four lobes. Write 5-6 cards for them before card 1; without them the nervous half covers cells, not anatomy.
  • Meninges: one layer out of three. Card 32 says the meninges have three layers, but only the dura mater gets a card. Add arachnoid mater (middle, with the subarachnoid space and CSF) and pia mater (inner, hugging the brain).
  • Disease vs syndrome. Card 75 defines Cushing's disease as excess cortisol "often due to a pituitary tumor". Strictly, Cushing's syndrome is excess cortisol from any cause, and Cushing's disease is the pituitary (ACTH-secreting adenoma) form. Rewrite the card with both terms, and link it to card 79 (pituitary adenoma). Card 71's "steroids, eicosanoids, amino acid derivatives" is also the older classification: most textbooks now teach peptide, steroid and amine hormones.

The deck is part of the Flip It anatomy series. For the 12 cranial nerves in their full anatomical context, continue with the Head, Neck and Spine anatomy study guide. For the cell side (membranes, ATP, signaling), see How to learn cell biology.

Open Flip It, search the library for Human Anatomy: Nervous & Endocrine (RP2466) and start with the pairs.
