EAR
Characteristics of the Ears
 2 Functions: 1. hear; 2. provide sense of
balance
 3 parts: 1. external ear; 2. middle ear; 3.
inner ear (aka labyrinth)
 We hear b/c sound waves vibrate through the
ear where they are transformed into nerve
impulses that are then carried to our brains
 Structures include auricle, tympanic
membrane (eardrum), ossicles, cochlea

MUSCULOSKELETAL
SYSTEM
Characteristics of the
Musculoskeletal System
Made up of muscles, bones, and joints
Body has 206 bones and 600+ muscles
Joints are located any place 2+ bones meet
Functions of muscular system => movement,
posture, joint stability, and heat production
 Functions of skeletal system => provide a
framework for body, protect soft body parts (ex
brain), store calcium, and produce blood cells
 List of structures and bones on pp.608-612
 Joints hold our bones together and make
movement (p.614)
 Muscles – skeletal, smooth, cardiac (p. 615-618)

Types of Body Movement
Abduction – movement of drawing away from the middle
Adduction - movement of drawing toward the middle
Inversion – turning away
Eversion – turning outward
Extension – movement in which a limb is placed in a
straight position
Flexion – movement in which a limb is bent
Pronation – movement that turns the palm down
Supination – movement that turns the palm up
Rotation – turning around its own axis
