Ability to move from place to place. The interaction between the skeleton & muscles result in body movement. Organisms that do not move are sessile and organisms that move are mobile.

ADVANTAGES OF MOTILITY

- Obtain food - Ability to disperse & migrate - Ability to seek shelter - Escape from predators - Find a mate increasing chances of survival of species

Provide support & protect body organs, provide a place for muscle attachment, Ca & P make them hard.

In the leg and arms have ends covered with cartilage and are capable of growth. Have living blood, fat & bone cells.

The outer covering is a tough membrane

Red and white blood cells produced in the inner tissue

Soft bone. It is fibrous, flexible, elastic connective tissue that provides flexibility and cushioning between bones. Found in adults in nose, ears, trachea, end of ribs, between vertebrae.

HUMAN MUSCULAR SYSTEM

Provides movement by pulling on bones when they contract.

Happens automatically such as heart contractions (cardiac muscle) or peristalsis. Smooth muscle is found in the walls of arteries and organs.

Can be controlled such as skeletal (striated muscle) which are attached to your bones.

Extends and straightens (ex: triceps)

Contract and bends the limb (ex: Bicep)

Both involuntary and voluntary muscle by sending nerve impulses to muscle causing them to contract.

Energy used to contract muscles is stored here

Glycogen is converted to glucose by this and stored in the liver.

Bands of dense tissue that connect muscle to bones.

Tough bands of tissue that hold bone together at joints. Connect bone to bone

Stay under the skin and can be closed

Stick out of the skin and can damage surrounding tissue

Tearing and stretching of ligaments. Caused by sudden twist or pull. Symptoms includes tenderness, swelling, bruising, inability to use joint.

An organ or tissue sticks out through a weak area in the muscle or tissue that contains it such as the abdomen wall. Caused by weakness in the wall. Symptom is a bulge or pain.

Causes stiffness, swelling, soreness and pain. Cortisone & other medication can be treatment.

Results from wear & tear on cartilage at joints

Causes swelling and pain at any age. Sometimes joints stiffen in deformed positions.

Inflammation of a tendon causing pain after extensive use.

Uric acid deposits in the joints symptom pain.

ADVANTAGES OF MOTILITY	- Obtain food - Ability to disperse & migrate - Ability to seek shelter - Escape from predators - Find a mate increasing chances of survival of species
BONES	Provide support & protect body organs, provide a place for muscle attachment, Ca & P make them hard.
LONG BONES	In the leg and arms have ends covered with cartilage and are capable of growth. Have living blood, fat & bone cells.
PERIOSTEUM	The outer covering is a tough membrane
MARROW	Red and white blood cells produced in the inner tissue
CARTILAGE	Soft bone. It is fibrous, flexible, elastic connective tissue that provides flexibility and cushioning between bones. Found in adults in nose, ears, trachea, end of ribs, between vertebrae.
HUMAN MUSCULAR SYSTEM	Provides movement by pulling on bones when they contract.
INVOLUNTARY MUSCLES	Happens automatically such as heart contractions (cardiac muscle) or peristalsis. Smooth muscle is found in the walls of arteries and organs.
VOLUNTARY MUSCLES	Can be controlled such as skeletal (striated muscle) which are attached to your bones.
EXTENSOR	Extends and straightens (ex: triceps)
FLEXOR	Contract and bends the limb (ex: Bicep)
NERVOUS SYSTEM	Both involuntary and voluntary muscle by sending nerve impulses to muscle causing them to contract.
GLYCOGEN	Energy used to contract muscles is stored here

FRACTURE	Broken bones
SIMPLE FRACTURE	Stay under the skin and can be closed
COMPOUND FRACTURE	Stick out of the skin and can damage surrounding tissue
SPRAINS	Tearing and stretching of ligaments. Caused by sudden twist or pull. Symptoms includes tenderness, swelling, bruising, inability to use joint.
HERNIA	An organ or tissue sticks out through a weak area in the muscle or tissue that contains it such as the abdomen wall. Caused by weakness in the wall. Symptom is a bulge or pain.
ARTHRITIS	Causes stiffness, swelling, soreness and pain. Cortisone & other medication can be treatment.
