SO-01 NEET Master Cheat Sheet
4 TISSUE TYPES Epithelial (cover/line, avascular) | Connective (most abundant, ECM) | Muscular (contract) | Neural (impulse)
EPITHELIUM MUST-KNOW
- Simple = 1 layer; Compound = multiple = PROTECTION
- Squamous: blood vessels + alveoli | Cuboidal: kidney tubules | Columnar: stomach/intestine | Ciliated: trachea + oviducts | Glandular: goblet cells
- All avascular; all on basement membrane
CONNECTIVE TISSUE MUST-KNOW
- LAD → Loose (Areolar: F+M+M; Adipose: fat storage)
- Dense → Regular (Tendon: muscle→bone; Ligament: bone→bone + elastin) | Irregular (dermis)
- Specialized → Cartilage | Bone (osteocytes/Ca-phosphate/Haversian) | Blood (plasma matrix)
- Blood = SPECIALIZED CT (not neural, not epithelial)
3 CARTILAGE TYPES Hyaline (trachea) | Elastic (ear pinna) | Fibrocartilage (intervertebral discs)
MUSCLE — THE MOST TESTED TABLE
| Skeletal | Smooth | Cardiac | |
|---|---|---|---|
| Striated | YES | NO | YES |
| Voluntary | YES | NO | NO |
| Nuclei | Many (peripheral) | 1 (central) | 1-2 (central) |
| Special | Fatigable | Sustained | Intercalated discs + Autorhythmic |
NEURAL Neuron: Dendrites → Cyton → Axon | Schwann = PNS myelin | Oligodendrocytes = CNS myelin
FROG FACTS (ALL 5)
- Heart: 3 chambers (2A+1V) + sinus venosus + truncus arteriosus
- Cranial nerves: 10 pairs (NOT 12)
- Excretion: Ureotelic + Mesonephric kidneys
- Respiration: Cutaneous + Buccopharyngeal + Pulmonary (skin must be moist)
- Reproduction: External fertilization; Male = vocal sacs + nuptial pads + Bidder's canal
TOP 5 NEET TRAPS
- Cardiac = STRIATED + INVOLUNTARY (only exception to "all striated = voluntary")
- Tendon = muscle-to-bone (NOT bone-to-bone — that is ligament)
- Blood = CONNECTIVE TISSUE (plasma = matrix)
- Epithelium = AVASCULAR (no blood vessels inside)
- Haversian system = BONE ONLY (not cartilage)
