100
What is the skeletal system function that provides a framework for the body?
support
100
What is the thick and thin filaments of a muscle fiber and where are they found?
myosin, actin, found in the sarcomere
100
What is the bone that is horseshoe shaped and has no articulation, and is it apart of the appendicular skeleton or the axial skeleton?
hyoid
100
What are the cells that are responsible for bone formation by secreting a matrix of organic compounds and mineral salts?
osteoblasts
100
What is the definition of muscles that are responsible for the primary action?
agonists (prime movers)
200
What is the function of yellow bone marrow?
Storage of Energy
200
What is the white fibrous connective tissue that surrounds the bone, except for the articular ends, and is essential for bone growth and repair? Is that tissue vascular or avascular?
Periosteum & vascular
200
What are the 3 parts of the sternum?
manubrium, xiphoid process, and the body
200
What is the muscle that plantar flexes the foot?
gastrocnemius
200
1. What is dense connective tissue that connects bone to bone? 2. What is dense connective tissue that connects muscle to a bone?
1. ligament 2. tendon
300
What is the ability of muscle tissue to receive and respond to a stimulus such as a nerve impulse ?
excitability
300
What is an action potential? What is the result of the first action potential in a motor unit?
membrane that has the potential to depolarize which would potentially cause an action. neuron depolarizes opens ca++ channel, calcium enters the synaptic bulb
300
What type of joint lacks a synovial cavity, articulates bones and are held tightly together by cartilage, and forms the disks in your vertebrae?
cartilaginous joints
300
What is the muscle tissue that the cells are separated by intercalated disks?
cardiac
300
What is the muscle that extends a flexed thigh or hyperextends the thigh from the anatomical position? what is the attatchment sight of a muscle with the least amount of mass?
Gluteus Maximus insertion
400
What is the ability of muscle tissue to return to its normal resting length after it has been stretched or contracted. what is ossification?
elasticity natural process of bone formation, hardening of tissue into bony substance
400
What are all the features of a long bone? Draw and label on your white boards Is compact bone vascular or avascular?
epiphysis, diaphysis, medullary cavity, periosteum, endosteum, spongy bone, compact bone, trabeculae, epiphyseal line, vascular
400
What are sac like structures that resemble joint capsules situated within body tissues?
bursae
400
What is the muscle that hyper extends the humerus in the anatomical position? What are the 4 primary functions of the muscular system? What are the 4 characteristics of the muscular system?
Latissimus Dorsi movement, stabalize joints, generate heat, posture excitability, contractability, elasticity, extensibility
400
What is a large rounded prominence which articulates with another bone? What is a muscle that functions to stabilize a point or body position?
condyle fixator(stabilizer)
500
What is the process of producing red blood cells? Which muscle tissue is not striated? what is the organization of a muscle?
Hematopoiesis smooth Muscle-->Fascicles--> Muscle fiber-->myofibrils-->sarcomeres-->myofilaments
500
What are all the bones in the foot from the tarsals to the phalanges? What 3 bones that form the hip bone?
tarsals, metatarsals, phalanges, calcaneus, talus, cuboid, navicular, lateral cuneiform, intermediate cuneiform, medial cuneiform illium, ischium, pubis
500
What are sutures and fontanels? What type of a joint do sutures form and where are they found?
sutures= "seam or stitch" found between skull bones fontanels= "soft spots" membrane filled spaces in between skull bones Fibrous joints are forms in between skull bones
500
What are the stem cells of the skeletal system? What 3 muscles are all directly involved with the movement of the humerus?
Osteogenic cells Pectoralis Major, Latissimus Dorsi, Deltoid
