Aims
Understand the common physiological
responses to injuries
Objectives
All students will be able to list some (all) of
the physiological responses to a muscle
strain
Some students will be able to explain the
physiological responses to a muscle strain

IntroductionPhysiological responses to injury
“An adjustment within cells, or
tissues, in response to an
environmental stimulus resulting
in an improved ability to cope
with the changing environment”

Grade 1 strain

Grade 3 strain
![Page 8: Sport injuries physiological resposes (muscle strain)](https://reader033.fdocuments.in/reader033/viewer/2022051411/5471c51cb4af9fbe0a8b4d67/html5/thumbnails/8.jpg)
Group Task
• In small groups reflect and identify the physiological responses as a result of a grade 3 muscle strain
• Think how does the body adapt and cope with the trauma

Activated platelets among a red blood cell

Healing process
• Absorption of swelling
• Removal of dead tissue
• Growth of new blood capillaries
• Development of fibrous tissue (scar tissue)

Individual task
• Complete the table in your own words describing the physiological responses to a grade 3 muscle strain
