SCAPULA BONE

Scapula bone has 17 to 18 muscle attachments. There is total of 639 muscles in our body out of which 634 are paired and the remaining 5 muscles are unpaired.in this post I am going to tell the pneumonics to remember the 18 muscle attachments that will be easy for students to remember and it will be a great help to my medical students.


the Scapula is known as the shoulder blade, it's a flat triangular bone with 2 surfaces coastal and dorsal surfaces with 3 angles superior, inferior and lateral angle, and lateral angle is known as the glenoid angle as well. the scapula bone has 3 borders as well superior border lateral border and medical border.

Scapula bone has 3 basic prominences tip of the coracoid process acromion process and crest of the spine of the scapula exactly crest of the spine is the structure that is present on the dorsal surface that separates into the supraspinous fossa and infraspinous fossa from where the respective muscles supraspinatus and infraspinatus takes its origin and supraspinatus initiate 15 degrees of abduction and subscapular fossa is present on the coastal surface from where subscapularis muscles take its origin

so here I am sharing a pneumonic to remember the origin and insertion of muscles. in diagram red part represents the origin and the blue part represents the insertion

SSC KI DOB BATLAI is for the origin

S-Supraspinatus

S-Subscapularis

C-Coracobrachialis

D-Deltoid

O-Omohyoid

B-Biceps brachii (short head)

BATLAI MEANS BATA DI

B-Biceps brachii (long head)

A- cut it no muscle start from A

T-3 muscles- Teres minor, triceps brachii( long head), teres major

L-Lattisimus dorsi is also known as climbing muscle

A- again cut it no muscle

I-Infraspinatus

Now the formula to remember insertion of muscles

S R L-------T R P

S- Seratus anterior

R-Rhoimboid minor

L-Levator scapulae

T-Trapezius

R- Rhoimboid major

P-Pectoralis minor

this will be very helpful for students to learn 18 muscle attachment of a human body

Demonstration of various anatomical position

Image
Demonstration of anatomical positions is very important for beginners in the medical field whether the student is studying medicine, dentistry, physiotherapy, medical lab technology, optometry by writing this article it will be a good help to students they will find this topic more simplified and easy. Aim: (a) Demonstration of various Anatomical Positions Equipment Required : N.A Materials Required : Model, Couch. Learning objectives A. To learn the basics of Anatomy B. Acquire the Knowledge of the skeletal system of our body. Outline of Procedures A. Model/Patient should be comfortable B. Examining part to be exposed enough to see and palpate the structures C. Identification of various parts of Body D. Identification of various positions Required Result: Parameters- The student will be able to elucidate the clinical findings. Relationships to be determined - NA Graphs/Plots-NA Error Analysis-NA Caution (if any): Bones and Models should be handled careful...

APPLICATIONS OF LASER THERAPY

Image
  Introduction: Physiotherapy, the practice of restoring movement and function to those affected by injury, illness, or disability, has evolved significantly over the years. One of the most groundbreaking advancements in this field is the integration of laser therapy. Laser therapy, also known as photo biomodulation therapy or low-level laser therapy (LLLT), utilizes light energy to stimulate healing and reduce pain. In this blog, we delve into the principles, applications, and benefits of laser therapy in physiotherapy. Understanding Laser Therapy: Laser therapy involves the use of specific wavelengths of light to penetrate the skin and stimulate cellular activity. These wavelengths interact with the body's tissues at a cellular level, triggering various physiological responses. Unlike surgical lasers that cut or burn tissue, therapeutic lasers used in physiotherapy deliver low levels of light that do not generate heat and are non-invasive. Mechanism of Action: At the cellular...

Motor points( Upper Limb)

Image
 Motor point is a small area on a muscle at which the minimal amount of electrical stimulation will cause muscle to contract. How to find motor point To locate your own  motor point  more accurately, you can move the positive electrode slightly (red cable) and watch where the muscle response is the best (strongest twitch of the same intensity). The  motor point  pen is an accessory that is sold separately in order to  find  the  motor point Motor points of upper limb Placement of electrodes is very important  red and black electrode cat is black black is active means pen electrode will be black while red one will be pad electrode. .
