PHARYNGEAL BRANCHIAL ARCH DERIVATIVES MNEOMONICS

First Pharyngeal Arch

Derivative of 1st Branchial Arch are a compilation of M and T:-

M-T

Muscles

2M4T

Mastication muscles (Temporalis,Masseter,Pterygoid)
Mylohyoid
Tensor tympani
Tensor veli palatini
Tongue- anterior two third
digasTric muscle- anterior belly

Skeletal

4M2T

Maxilla
Malleus + incus
Meckel cartilage
sphenoMandibular ligament
Temporal bone- squamous part
zygomaTic

Nerve

MT

Mandibular division of Trigeminal nerve

Artery

Maxillary artery

Second Pharyngeal Arch

Derivative of 2nd Branchial Arch can be learnt as S and as:-

S

Muscles

Stapedius
Stylohyoid
Smile- muscles of facial expression
BAPP as-
Buccinator
Auricular muscles
Platysma
Posterior belly of digastric muscle

Skeletal

Stapes
Styloid process
Stylohyoid ligament
lesser cornua and upper half of body of hyoid
reichert's cartilage

Nerve

Seventh nerve (facial nerve)

Artery

Stapedial artery
hyoid artery

Third Pharyngeal Arch

Derivatives of 3rd Branchial Arch are like GlossoPharyngeus, that is, GP:-

GP

Muscles

styloPharyngeus

Skeletal

Greater cornea and lower half of hyoid

Nerve

GlossoPharyngeal nerve

Arteries

common carotid artery and internal carotid artery

Fourth Pharyngeal Arch

Derivatives of 4th Branchial Arch can be traced back to Thyroid:-

Muscle

cricoThyroid
pharyngeal constrictors
levator veli palatini

Skeletal

Thyroid cartilage
epiglottic cartilage

Nerve

superior laryngeal nerve

Artery

4th left- Aortic arch
4th right- Subclavian arch

Sixth Pharyngeal Arch

Derivative of 6th Branchial Arch can be traced back to Larynx as:-

Muscles

Larynx- all intrinsic muscles except cricothyroid

Skeletal

Larynx- all cartilages except thyroid (cricoid,corniculate,cuneiform and arytenoid)

Nerve

Laryngeal nerve- recurrent

Artery

6th left- Pulmonary artery and Ductus arteriosus
6th right- Pulmonary artery

This is a way to learn the derivatives of pharyngeal arches. But it's always better to understand things than to mug up.
-Learning nerve supply followed by derivatives is highly recommended because that will make your basics further strong.
