Basic Anatomy

The skeleton is

the framework for

the body.

It includes 206

bones of various

sizes and types.

Skeletal and Muscular System Midline: the median line of the body; lines up with the nose, naval, pubic

synthesis and heels

Origin: the point at which a muscle begins; closest to the midline

Insertion: the point at which a muscle ends; farthest from the midline

Action: the function or the performance of a function of the body or one of its

parts

Joint: the point of contact between elements of a skeleton whether movable or

rigidly fixed together with the surrounding and supporting parts (as membranes,

tendons, or ligaments)

JointsJoint types identify how joints move, their strengths, and their limitations.

•Ball-and-socket joints: an articulation (as the hip joint) in which the rounded head of one bone fits into a cuplike cavity of the other and admits movement in any direction

•Examples- hip and shoulder joints

•Hinge joints: formed between two or more bones where the bones can only move along one axis to flex or extend

•Examples- elbow, finger, knee, and toe joints

Connective Tissue

Two types of tissue connect bones and muscles: ligament and tendon.

A ligament is a strong band of tissue that connects bone to bone.

A tendon is a strong band of tissue that connects muscle to the bone.

Dance Fitness

• Strength is the amount of force a muscle can produce. You need strength to dance.

• Flexibility is the ability to extend

• Endurance is the ability to sustain a prolonged stressful effort or activity

Alignment

Achieving good vertical

alignment requires correctly

positioning the parts of the body.

Alignment: placement of body parts

Physical Preparation

RICE: Rest, Ice, Compression, Elevation; used in treatment of

injuries

Strain: to injure by overuse, misuse, or excessive pressure

Sprain: a sudden or violent twist or wrench of a joint causing

the stretching or tearing of ligaments

Injury: hurt, damage, or loss sustained
