This document provides an overview of a first aid course, including its subject, total hours, units, and unit details. The course covers first aid for emergencies over 20 hours divided into 3 units. Unit 3 focuses on first aid for asphyxia, drowning, shock, wounds, injuries to bones/joints/muscles like fractures and strains, burns, scalds, poisoning, and foreign objects. It describes ligaments, tendons, muscle strains, sprains, hanging, strangling, falls, and scalding injuries as well as treatment approaches. The unit aims to educate students on providing first aid for various emergency situations.

30. 1) Bone

31. 2) Joint

32. 3) Ligament & tendon
A ligament is the fibrous connective tissue that
connects bones to other bones. It is also known
as articular ligament, articular larua, fibrous ligament,
or true ligament.
A tendon or sinew is a tough band of fibrous connective
tissue that connects muscle to bone and is capable of
withstanding tension.

34. strain
A muscle strain, or pulled muscle, occurs when your
muscle is overstretched or torn. This usually occurs as a
result of fatigue, overuse, or improper use of a muscle.
Strains can happen in any muscle, but they’re most
common in your lower back, neck, shoulder, and
hamstring, which is the muscle behind your thigh.

35. sprain
A sprain is a stretching or
tearing of ligaments — the
tough bands of fibrous tissue
that connect two bones
together in your joints. The
most common location for a
sprain is in your ankle.

47. 1) Hanging

48. 2) Strangling

49. Strangling is compression of the
neck that may lead
to unconsciousness or death by
causing an
increasingly hypoxic state in the
brain.[1] Fatal strangling typically
occurs in cases of violence,
accidents, and is one of two main
ways that hanging causes death
Manual strangulation (also
known as "throttling") is strangling
with the hands, fingers, or other
extremities and sometimes also
with blunt objects, such
as batons.

52. Falls

68. Scalds
Scalding (from the Latin word calidus, meaning hot[1]) is a form of thermal
burn resulting from heated fluids such as boiling water or steam. Most scalds
are considered first or second degree burns, but third degree burns can
result, especially with prolonged contact.
