Positive Healthy Habits
such as exercising daily, getting quality sleep, and following good hygiene habits can help
decrease stress, lower the risk of disease, and increase energy.
Human Skeletal System
provides internal framework to support the body, protects organs, and enables movement with
the muscular system. Consists of bones, cartilages, ligaments, and tendons and account for 20%
of the body weight.
Bones
provide the rigid skeleton that constitutes the internal framework the body needs to stand.
Skeleton
supports and protects the soft organs of the body. Usually consists of 206 bones - long, short, flat,
and irregular bones.
Joint
also referred to as an articulation, is where two bones come together. 3 categories: immovable,
slightly movable, and freely movable.
Cartilage
is the tough but flexible tissue that covers the ends of the bones of freely movable joints and
protects bones by preventing them from rubbing against each other.
,Ligament
is a connective tissue that binds one bone to another. It usually helps hold structures together and
allows for side-to-side stability.
Tendon
is a connective tissue that attaches muscle to bone. Aids in the movement of the bone or
structure.
Achilles Tendon
connect the calf muscle to the heel bone.
The Muscular System
enables the heart to beat, the chest to rise and fall during breathing, and the blood vessels to help
regulate the pressure and flow of blood through the body.
3 Types of Muscles in The Body
Striated muscle - is also known as skeletal muscle. It moves all bones and controls facial
expressions and eye movements.
Smooth muscle - or visceral muscle, lines the walls of internal organs, such as the intestines.
Cardiac muscle - is a unique type of muscle. It is a combination of both striated and smooth
muscle. Only the heart has cardiac muscle.
The Nervous System
- the control center for all actions that occur consciously and unconsciously and the
communication among the body parts.
, - more than 100 billion nerve cells operate constantly all over the body to coordinate involuntary
activities.
- is the major controlling, regulatory, and communicating system in the body.
- functions include receiving sensory input, sending signals to the brain, regulating homeostasis,
and communicating throughout the body for movement.
2 Major Divisions of the Nervous System
Central nervous system - the brain and the spinal cord, comprise the CNS. Messages in the CNS
travel through the spinal cord to the brain, and the brain, in response, directs all the functions of
the body.
Peripheral Nervous System - consists of all the nerves outside of the brain and spinal cord. These
nerves relay messages between the CNS and other areas of the body, including the internal
organs and glands, abdomen, chest, arms, and legs. Also inner gates and communicates with the
sensory organs: eyes, ears, nose, and mouth. Refers to the nerves that are outside of the brain and
spinal cord.
The Respiratory System
works with the cardiovascular system to provide oxygen to the cells and to remove the waste
products. Triggers breathing.
Lungs
the primary organ of the respiratory system which exchange gases during the breathing process.
Respiratory passages
