The interaction of muscles with the skeleton that
results in body movement
How does locomotion increase chances for survival?
Locomotion increases the chances for survival of an
organism by allowing the organism to gather food,
seek shelter, and escape dangerous situations and by enabling members of the species to
find suitable mates
Human locomotion involves
the interaction of joints and tissues such as bone, cartilage, muscles,
tendons and ligaments
a type of connective tissue.
Facts about bones
The hardness of the bone is due to the
presence of calcium and phosphorus
Bones make up the major part of the
framework of the human skeleton and come
in many shapes and sizes.
Bones support and protect body organs.
Bones also provide a place for muscle
bones of your legs and arms
where red and white blood cells are produced in
the inner tissue
acts as a
framework for supporting other organs of the body.
It also protects internal organs and allows body
The human skeleton has 206 bones.
It is composed of a skull, vertebral column (spinal
column), breastbone and ribs, and limbs (arms and legs).
fibrous, flexible, elastic connective tissue
found in the human skeleton
Where is cartilage found?
In the human embryo, the skeleton is made up mostly of cartilage.
By adulthood, most of the cartilage has been
replaced by bone.
In the adult, cartilage is found in the nose, ears, and trachea, at the ends of ribs and other bones and between the vertebrae.
What are features of cartilage?
At the ends of bones, cartilage provides flexibility
Between bones, cartilage provides
In the ears, nose, and trachea, cartilage provides flexible, rather than rigid support.
the places where bones are connected
Ball and socket joints
located at the hip and shoulder.
They permit circular movement.
located at the elbows and knees.
They allow a back and forth movement.
Hinge joints do not permit as much movement as
ball and socket joints.
found where the skull joins the vertebral column
Pivot joints permit a rotating movement
The wrist and ankle have gliding joints that
allow a sliding action
not movable and are located in the skull
produce body movement by pulling on bones when they contract.
Muscles also produce body heat when they contract.
Muscles can be voluntary or involuntary
are responsible for involuntary body activities such as heart contractions and peristalsis
You cannot control the actions of involuntary muscles.
Smooth muscle and cardiac muscle are examples of involuntary muscles.
attach to the skeleton and can be controlled for locomotion
Skeletal (striated) muscle
type of voluntary muscle, attached to
the bones of the skeleton
provides the energy needed for muscles to
produced by muscles during anaerobic respiration, causes muscles to hurt (muscle fatigue), rest will supply oxygen to muscles which is needed- if you don't rest permanent injury to the muscle can occur
Tendons and ligaments
both composed of connective tissue, tendons connect muscles to bones, tendons hold bones together at joints
broken bones. caused by a sudden injury that exerts more force on the bone than it can support
common symptom of a fracture is swelling and
tenderness at the place of the fracture.
Pain is often severe and is usually made worse by any movement of the area.
Anyone suffering a suspected or known fracture should be taken to a hospital.
A tearing or stretching of this ligaments that hold together the bone end in a joint, caused by a
sudden pull or twist, suspected strains should be x-rayed to make sure it is not a fracture
an organ or tissue sticks out through a weak area in the muscle or other tissue that usually contains it such as the abdominal wall.
The cause is usually a weakness in the wall.
The first symptom is a bulge in the wall.
An inflammation of the joints, causes stiffness, swelling, soreness, or pain.
Sometimes the joints stiffen in a deformed position.
Cortisone and other medications are used on the treatment of arthritis.
inflammation of a tendon, usually at the bone junction.
Usually pain is felt in the wrist or ankle after extensive use such as running or even using a
other muscle bone disorders
scoliosis, osteoporosis and cervical spine trauma
