Test 1 - Basic Anatomy

What are the types of cells found in nervous tissue

neurons and glial cells

lateral

away from the midline of the body

deep

on the inside

superficial

on the outside

proximal

closest to the point of attachment to the trunk

distal

furthest from the point of attachment to the trunk

What are the specific types of cartilage(s) found in the human body

fibrocartilage, elastic cartilage, hyaline cartilage

Growth, maintenance, and repair of our bones depends on what

hormones, exercise, vitamins

epimysium

covers bundles of fascicles called skeletal muscle

perimysium

covers bundles of muscle fibers called fascicles

endomysium

covers individual muscle fibers

What are the various functions of our body's blood

transport, waste removal, nutrient delivery, immune defense, and tissue repair

Ligaments connect skeletal muscle to bone

False

anterior

front

posterior

back

superior

closer to the head

inferior

closer to the feet

medial

toward the midline of the body

Explain the Sliding Filament Theory

calcium exposes actin, myosin binds and pulls using ATP, shortening the muscle, then resets when calcium returns to the sarcoplasmic reticulum

homeopoiesis is the process of blood cell production in red bone marrow

True

synergists

assist the prime mover

antagonists

relax when the prime mover contracts

agonist

performs most of the movement

coronal plane

divides body into anterior and posterior

transverse plane

cuts perpendicular to the long axis

midsagittal plane

divides body into equal right and left halves

oblique plane

passes through at an angle

What are the 3 protein fibers of connective tissue proper

elastic fibers, collagen fibers, reticular fibers

exercise helps maintain density and prevent osteoporosis

Tendons connect skeletal muscle to bone

True

Select ALL the functions of connective tissue

physical protection, immune protection, transport, binding of structures, storage, support and structural framework

What is the difference between loose connective tissue and dense connective tissue

loose has fewer protein fibers and more ground substance

What are the different histological types of muscle in the body

smooth muscle tissue, skeletal muscle tissue, cardiac muscle tissue

What are the BROAD categories of connective tissue

connective tissue proper, fluid connective tissue, supporting connective tissue

Excitability

ability to respond to stimuli

conductivity

ability to transmit electrical events

contractility

ability to generate tension and shorten

elasticity

ability to return to resting length

extensibility

ability to be stretched beyond resting length

What happens to a person's muscle mass as they age

muscle mass decreases due to hormonal and structural changes

What is the function(s) of our body's cartilage

support soft tissue, provide smooth joint surfaces, and aid in bone formation
