Support
What is the skeletal system function that provides a framework for the body?
100
Myosin, Actin, Found in the sarcomere
What is the thick and thin filaments of a muscle fiber and where are they found?
100
hyoid
What is the bone that is horseshoe shaped and has no articulation, and is it apart of the appendicular skeleton or the axial skeleton?
100
osteoblasts
What are the cells that are responsible for bone formation by secreting a matrix of organic compounds and mineral salts?
100
Prime Movers or agonists
What is the definition of muscles that are responsible for the primary action?
200
Storage of Energy
What is the function of yellow bone marrow?
200
Periosteum & vascular
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?
200
manubrium, xiphoid process, and the body
What are the 3 parts of the sternum?
200
gastrocnemius
What is the muscle that plantar flexes the foot?
200
ligament
What is dense connective tissue that connects bone to bone?
300
excitability
What is the ability of muscle tissue to receive and respond to a stimulus such as a nerve impule
300
membrane that has the potential to depolarize which would potentially cause an action. neuron depolarizes opens ca++ channel, calcium enters the synaptic bulb
What is an action potential? What is the result of the first action potential in a motor unit?
300
cartilaginous joints
What type of joint lacks a synovial cavity, articulates bones and are held tightly together by cartilage, and forms the disks in your vertebrae?
300
cardiac
What is the muscle tissue that the cells are separated by intercalated disks?
300
Gluteus Maximus insertion
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?
400
elasticity natural process of bone formation, hardening of tissue into bony substance
What is the ability of muscle tissue to return to its normal resting length after it has been stretched or contracted. what is ossification?
400
epiphysis, diaphysis, medullary cavity, periosteum, endosteum, spongy bone, compact bone, trabeculae, epiphyseal line, vascular
What are all the features of a long bone? Draw and label on your white boards Is compact bone vascular or avascular?
400
bursae
What are sac like structures that resemble joint capsules situated within body tissues?
400
Latissimus Dorsi movement, stabalize joints, generate heat, posture excitability, contractability, elasticity, extensibility
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?
400
condyle fixator(stabilizer)
What is a large rounded prominence which articulates with another bone? What is a muscle that functions to stabilize a point or body position?
500
Hematopoiesis smooth Muscle-->Fascicles--> Muscle fiber-->myofibrils-->sarcomeres-->myofilaments
What is the process of producing blood cells in the red bone marrow? which muscle tissue is not striated? What is the organaztion and structure of a muscle?
500
tarsals, metatarsals, phalanges, calcaneus, talus, cuboid, navicular, lateral cuneiform, intermediate cuneiform, medial cuneiform illium, ischium, pubis
What are all the bones in the foot from the tarsals to the phalanges? What 3 bones form the hip bone?
500
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
What are sutures and fontanels? What type of a joint do sutures form and where are they found?
500
Osteogenic cells Pectoralis Major, Latissimus Dorsi, Deltoid
What are the stem cells of the skeletal system? What 3 muscles are all directly involved with the movement of the humerus?
500
zygomatic ethmoid spina bifida
-What are the cranial bones that form the cheek bones? -What is a light spongy bone located in the anterior part of the floor of the cranium between the orbits? -What skeletal dissorder is caused when the posterior part of the vertebrae fails to form properly and does not enclose the spinal cord?
