Origin:
Thoracis: Sacrum, Iliac Crest and Transverse Processes of L1 - L5
Cervicis: Transverse Processes of T1 - T5
Capitis: Transverse Processes of T1 - T5 and Articular Processes of C5 - C7
Insertion:
Thoracis: TPs of All the Thoracic Vertebrae and the Lower 9 Ribs
(Between Their Tubercles and Angles)
Cervicis: TPs of C2 - C6
Capitis: Mastoid Process of Temporal Bone
Functions:
1- Extension of the Head @ the Atlanto-Occipital Joint
2- Extension of the Neck @ the Spinal Joints
3- Extension of the Trunk @ the Spinal Joints
4- Lateral Flexion of the Head @ the Atlanto-Occipital Joint
5- Lateral Flexion of the Neck @ the Spinal Joints
6- Lateral Flexion of the Trunk @ the Spinal Joints
7- Anterior Tilt of the Pelvis @ Lumbo-Sacral Joint
8- Ipsilateral Rotation of the Head @ the Atlanto-Axial Joint
9- Ipsilateral Rotation of the Neck @ the Spinal Joints
10- Ipsilateral Rotation of the Trunk @ the Spinal Joints
Nerve:
Dorsal (Posterior) Rami of the Spinal Nerves at the Corresponding Levels
Activation: Extension, Lateral Flexion, Ipsilateral Rotation of the Trunk, Neck, Head
Lengthening: Flexion, Lateral Flexion (Opposite), Contralateral Rotation of the Trunk, Neck, Head

Do you have any tips to remember the insertion points of these muscle groups? They are quite confusing to memorize and I am afraid that it will be asked in the board exam.
Thank you

I have a fun one for you.
Creating a mnemonic using Marvel characters to remember the origin and insertion of the Longissimus muscle can be both fun and effective. The Longissimus is part of the erector spinae muscle group and primarily acts to extend and laterally flex the spine. Let's break down its origin and insertion points and then craft a mnemonic.
Origin and Insertion of the Longissimus Muscle:
Origin: The Longissimus originates from the transverse processes of T1-T5 thoracic vertebrae, and the articular processes of the C4-C7 cervical vertebrae.
Insertion: It inserts into the mastoid process of the temporal bone, the transverse processes of the upper thoracic vertebrae, and the cervical vertebrae up to C2.
Mnemonic Creation:
Let's use Marvel characters to remember this. Imagine a storyline where Loki (representing the Longissimus muscle) is trying to Originate a plan from Tesseract pieces (T1-T5) and Artifacts from Captain America (C4-C7), aiming to Insert them into Mjolnir (Mastoid process), with the help of Thor (Thoracic vertebrae) and Captain (Cervical vertebrae up to C2).
Mnemonic:
"Loki's Origin Tactic: Tesseracts and Captain's Artifacts for Mjolnir's Insertion with Thor and Captain."
Loki's Origin Tactic: Reminds you of the Longissimus muscle's origin.
Tesseracts (T1-T5) and Captain's (C4-C7) Artifacts: Symbolize the origin points from the thoracic and cervical vertebrae.
Mjolnir's Insertion: Represents the insertion into the mastoid process.
With Thor and Captain: Thor symbolizes the thoracic vertebrae, and Captain (up to C2) represents the cervical vertebrae.
This story-based mnemonic incorporates Marvel characters and elements to help you remember the origin and insertion points of the Longissimus muscle in a more memorable and enjoyable way.
