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

Chapter 14

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 awayEversion – turning outwardExtension – movement in which a limb is placed in

a straight positionFlexion – movement in which a limb is bentPronation – movement that turns the palm downSupination – movement that turns the palm upRotation – turning around its own axis
