HCA 121: Module 1
Epithelial tissue - ANS covers internal and external body surfaces
Connective tissue - ANS anchors, connects, and supports other tissues
Muscle tissue - ANS stretches and contracts to let the body move
Nerve tissue - ANS receives and carries impulses to the brain and back to body parts
How many organ systems do humans have - ANS 11
What is the largest system - ANS Integumentary
The two skin layers - ANS Dermis and Epidermis
The outer layer of the skin - ANS Epidermis
The inner layer of the skin - ANS Dermis
What slows the growth of bacteria of the skin's surface? - ANS Oil
What prevents microorganisms and other substances from entering the body? - ANS Body's
protective covering
What senses both pleasant and unpleasant stimulation? - ANS Nerve endings
System that provides the framework for the body? - ANS Musculoskeletal system
Functions of Musculoskeletal system - ANS lets the body move, protect and give the body
shape, consist of bones, muscles, ligaments, tendons and cartilage
5 types of bones - ANS long, short, flat, irregular, sesamoid
Bear the body's weight - ANS Long bone
Allow skill and ease in movement - ANS Short bones
Protect organs - ANS Flat bones
Allow various degrees of movement and flexibility - ANS Flat bones
, Short and irregular and protect tendons - ANS Sesamoid bones
Point at which two or more bones meet - ANS Joint
6 Types of joints - ANS Ball and socket joints, hinge joints, pivot joints, saddle joints, gliding
joints, condyloid joints
Allow movement in all direction - ANS Ball and socket
Allow movement in one direction - ANS Hinge joints
Allow turning from side to side - ANS Pivot joints
Allow for a wide range of motion - ANS Saddle joints
Allow for limited but complex guiding movements - ANS Gliding joints
Wrists and knuckles - ANS Condyloid joints

3 Types of muscles - ANS Skeletal, smooth and cardiac muscles
3 Functions of Muscles - ANS - Movement of body parts
- Maintenance of posture
- Production of body heat
Nervous System - ANS - controls, directs, and coordinates body functions
2 Main Divisions of Nervous System - ANS CNS and PNS
2 main parts of the brain - ANS Cerebellum, cerebrum, brainstem
Lies within the spinal column and contains pathways that conduct messages to and from the
brain and spinal nerves - ANS Spinal cord
3 layers of connective tissue that covers and protects brain and spinal cord - ANS Dura mater,
arachnoid, pia mater
Outer layer (Nervous system) that lies next to the skull - ANS Dura mater
Middle layer (Nervous System) - ANS Arachnoid
Inner layer (Nervous system) - ANS Pia Mater
