What does this Anatomy & Physiology cheat sheet cover?

It has 10 sections: Anatomical Terms, Tissues, Skeletal System, Muscle Contraction, Nervous System, Endocrine, Cardiovascular, Respiratory, Digestive and Urinary & Immune. Together they cover the topics a typical Anatomy & Physiology exam tests, including anatomical terms and planes, tissue types, skeletal system and muscle contraction.

Is the anatomy and physiology cheat sheet free?

The first part is free to read on this page, with no account needed. The full sheet opens in the app with Unlimited ($4.99 a month or $19 for a semester), where you can edit it, print it or save it as a PDF. It is one US Letter page and prints cleanly in black and white or colour.

Can I bring this Anatomy & Physiology cheat sheet to my exam?

Only if your course allows a note sheet, so check the syllabus. This one is a single US Letter page. If your exam allows a different size, such as a 3x5 or 4x6 index card or one page front and back, Cheat Sheet AI makes one at exactly that size from your own lecture notes.

The sheet was written by our engine from a standard course outline, then a second model fact-checked every formula and statement against it; it corrected 2 statements before publishing. Notation and emphasis vary between courses, so check it against your own lecture notes.

Can I make a Anatomy & Physiology sheet from my own notes?

Yes. Upload your lecture slides, notes or study guide and Cheat Sheet AI writes a sheet in your course's notation, sized to exactly the space your exam allows. Your first sheets are free.

01Anatomical Terms

Anatomical position: Standing upright, feet flat and forward, arms at sides, palms forward.

Directional terms

Term	Meaning	Opposite
$superior$ / $cranial$	toward head	$inferior$ / $caudal$
$anterior$ / $ventral$	front	$posterior$ / $dorsal$
$medial$	toward midline	$lateral$
$proximal$	near origin/trunk	$distal$
$superficial$	near surface	$deep$

Planes

Plane	Divides
$sagittal$	left/right
$midsagittal$	equal left/right
$frontal$ / $coronal$	anterior/posterior
$transverse$ / $horizontal$	superior/inferior
$oblique$	angled cut

Body cavities: $dorsal$ = cranial + vertebral; $ventral$ = thoracic + abdominopelvic.

Abdominopelvic regions

Quadrant	Main contents
$R U Q$	liver, gallbladder
$LU Q$	stomach, spleen
$R L Q$	appendix
$LL Q$	sigmoid colon

Watch out:Use $right / left$ of the patient, not the observer.

02Skeletal System

Compact bone unit

osteon = concentric lamellae around a central (Haversian) canal

compact bone microstructure

Joints

Type	Movement
$fibrous$	little/none
$cartilaginous$	slight
$synovial$	free

Synovial joint features

Structure	Role
Articular cartilage	reduces friction
Synovial fluid	lubricates
Ligament	bone to bone
Tendon	muscle to bone

Watch out:Bone remodeling: $osteoclast$ resorption balanced by $osteoblast$ deposition; imbalance ⇒ osteoporosis.

03Muscle Contraction

Sarcomere: Basic contractile unit between $Z$ discs in striated muscle.

Sliding filament


Ca^{2+} + troponin \rightarrow tropomyosin shift \rightarrow myosin-actin cross-bridges

Key proteins

Protein	Role
Actin	thin filament
Myosin	thick filament, ATPase
Troponin	binds $C a^{2 +}$
Tropomyosin	blocks actin sites at rest

Contraction cycle

Step	Event
1	ATP hydrolysis cocks myosin
2	myosin binds actin
3	power stroke
4	new ATP detaches myosin

04Nervous System

Watch out:Myelin increases conduction speed by limiting depolarization to nodes of Ranvier.

05Endocrine

Hormone: Chemical messenger released into blood to act on target cells with specific receptors.

Major glands

Gland	Main hormones
Hypothalamus	releasing/inhibiting hormones; synthesizes $A D H$ and oxytocin
Anterior pituitary	$G H$ , $T S H$ , $ACTH$ , $F S H$ , $L H$ , $P R L$
Posterior pituitary	releases $A D H$ , oxytocin
Thyroid	$T_{3}$ , $T_{4}$ , calcitonin
Parathyroid	PTH
Adrenal cortex	cortisol, aldosterone
Adrenal medulla	epinephrine, norepinephrine
Pancreas	insulin, glucagon

Blood glucose

Hormone	Effect
Insulin	decreases glucose
Glucagon	increases glucose

Feedback

Type	Example
Negative	most endocrine control
Positive	oxytocin during labor, LH surge

Target cell: Cell with receptor for a given hormone; specificity is receptor-based, not blood delivery alone.

06Respiratory

Gas exchange

$O_{2} $ diffuses : alveoli$ → $blood$ , \quad CO_2 : $blood$ →$ alveoli

down partial pressure gradients

Ventilation formula

minute ventilation = tidal volume $\times$ respiratory rate

air moved per minute

Breathing muscles

Action	Muscles
Inspiration	diaphragm contracts; ribs up
Forced expiration	internal intercostals, abdominals

Surfactant: Lowers alveolar surface tension; prevents collapse.

Watch out:Most $C O_{2}$ is transported as $H C O_{3}^{-}$ in blood, not dissolved gas.

07Digestive

GI tract order

Segment	Main function
Mouth	ingestion, chewing, salivary amylase
Esophagus	peristalsis
Stomach	acid + pepsin, mixing
Small intestine	digestion + absorption
Large intestine	water absorption, feces

Accessory organs

Organ	Secretion / role
Liver	bile production
Gallbladder	stores bile
Pancreas	enzymes + bicarbonate
