Features of Carpal bones and their centres of ossification.

The name and sequence of carpal bones can be memorized using a simple mnemonic.

Mnemonic: Please Take Little Susy To The Coffee House

  1. Pisiform
  2. Triqueteral
  3. Lunate
  4. Scaphoid
  5. Trapezium
  6. Trapezoid
  7. Capitate
  8. Hamate

While counting start from pisiform which is the Medial most in first row and count to lateral and from there jump to the 2nd row and count from lateral to medial.

Pisiform is a sesamoid bone lying within tendon of Flexor Carpi Ulnaris

Largest carpal bone- Capitate

Carpal bone with Hook -Hamate

First Carpal bone to Ossify- Capitate

Last carpal bone to ossify- Pisiform

Most Commonly fractured carpal bone- Scaphoid

Ossification centres in carpal bones

  1. Capitate- 2nd month
  2. Hamate- 3rd month
  3. Triquetral- 3rd year
  4. Lunate- 4th year
  5. Scaphoid -4th-5th year
  6. Trapezium- 4th-5th year
  7. Trapezoid- 4th-5th year
  8. Pisiform- 9th -12th year

 

Mnemonic for 12 cranial nerves and their types.

We know that there are 12 pairs of cranial nerves which originate from the brain and brainstem. Remembering the names of these cranial nerves is easily mastered but it is difficult to remember their type ie whether they are Sensory nerves, motor nerves or mixed nerves.

  1. Olfactory
  2. Optic
  3. Oculomotor
  4. Trochlear
  5. Trigeminal
  6. Abducens
  7. Facial
  8. Auditory/Vestibulocochlear
  9. Glossopharyngeal
  10. Vagus
  11. Spinal Accessory
  12. Hypoglossal

A simple mnemonic will help you to remember the types of cranial nerves.

Mnemonic: Some Say More Money But My Brother Says Big Books Matter More

S Represents sensory nerves, M represents Motor and B -represents Both/Mixed nerves.

So the Cranial nerves and their types become.

  1. Olfactory – Some -Sensory
  2. Optic- Say- Sensory
  3. Oculomotor- More- Motor
  4. Trochlear- Money- Motor
  5. Trigeminal- But – Mixed
  6. Abducens- My- Motor
  7. Facial- Brother- Mixed
  8. Auditory/Vestibulocochlear- Says- Sensory
  9. Glossopharyngeal- Big- Mixed
  10. Vagus- Books- Mixed
  11. Spinal Accessory- Matter- Motor
  12. Hypoglossal- More- Motor

Learn the exit routes of cranial nerves with the picture given below.
