Basic Anatomy
The skeleton is
the framework for
the body.
It includes 206
bones of various
sizes and types.
Muscular System

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)
Joints
Joint 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
