Muscles Flashcards
What are the 3 types of muscles?
Skeletal, Smooth, and cardiac
what are Ligaments?
Tissue that connects bone to bone
What are tendons?
Tough bands of connective tissue that joins muscle to bone.
what are Fascia?
connective tissue that covers, supports, and seperates muscles.
What is Tissue?
Masses of cells that have similar function and form
what is muscle tissue
a collection of cells that shorten during contraction, therefore creating tension that results in movement
What is Skeletal Muscle?
Muscles that are attached to bones vie connective tissue tendons
is Skeletal muscle fatigue-resistant?
No
What is smooth muscle?
Muscles surrounding body’s internal organs+ blood vessels, respiratory tract, Iris(eye), and gastrointestinal tract
Their contractions are…
Slow and uniform and can be sustained for a long period of time.
their activation is…
involuntary
is smooth muscle fatigue resitant?
Yes
What is Cardiac Muscle?
Found only in the heart, contracts the heart, and is very fatigue resistant.
What is epimysium?
the connective tissue surrounding the whole muscle
What is perimysium?
connective tissues surrounding each fascicle.
what is a fascicle?
perimysium wrapped muscle fibers
What is endomysium?
the connective tissue surrounding each muscle fibre
what is muscle fibre?
a muscle cell
The ability of muscle to respond to stimulus?
Irritability
Ability to transmit nerve impulses?
conductivity
ability to shorten in length?
Contractibility
ability to extend in length?
extensibility
Ability to stretch and return to normal position?
elasticity
Concentric contraction is?
when muscle fibres shorten
Eccentric contraction is?
when muscle fibres lengthen
when muscle fibres don’t change length?
Isometric
Vastus?
Huge
Maximus?
Large
Longus?
Long
Minimus?
Small
Brevis?
Short
Deltoid?
triangular
Rhomboid?
like a rhombus with equal and parallel sides
Latissimus?
Wide
Teres?
Round
Trapezius?
Like a trapezoid
Rectus?
Straight
Transverse?
Across
Oblique?
Diagonally
Pectoralis?
Chest
Gluteus?
Buttock
Brachii?
Arm
Supra?
Above
Infra?
below
Sub?
under or beneath
laterallis?
lateral
Abductor?
Moves parts of the body away
Adductor?
moves parts of the body toward
Flexor?
causes a joint to bend, decreasing joint angle
extensor?
causes a joint to straighten
Lavator?
lifts a structure
What are the 3 Hamstrings muscles?
Biceps femoris, semimembranosus, and semitendonosus
what are the 3 gluteal muscles?
Gluteus Maximus, Gluteus Medius, Gluteus Minimus
what are the 4 Quadriceps femoris muscles?
Rectus Femoris, vastus lateralis, vastus intermedius, vastus medialis
What are the 5 Muscles pairs
Biceps+Triceps Quads+hamstrings Deltoid+Latissimus Dorsi Gastrocnemius and soleus+Tibialis Gluteus Medius and minimus+ adductor Magnus
