Connective Muscle

Question 1

What are the three types of muscle

Answer 1

Skeletal, cardiac, and smooth

Question 2

Where is skeletal located

Cardiac? Smooth?

Answer 2

Skeletal:attached to bones or occasionally skin
Cardiac: walls of the heart
Smooth: walls of hollow organs

Question 3

What is smooth muscle

Answer 3

Spindle shaped cells with central nuclei, no striations, arranged to form close sheets

Question 4

What is the function of smooth muscle

Answer 4

Involuntary control, propels objects along internal passageways

Question 5

Function of sketeltal

Answer 5

Voluntary movement, locomotion, voluntary control

Question 6

What is skeletal muscle

Answer 6

Long, cylindrical, multinucleate cells, with striations

Question 7

What is cardiac muscle

Answer 7

Branching, striated, unicleate cells

Question 8

Function of cardiac muscle

Answer 8

As it contracts, it propels blood into circulation.

Question 9

Connective tissue

Answer 9

Consist of living cells surrounded by matrix

Arise from a common embryonic tissue called mesenchyme.

Question 10

4 types of connective tissues

Answer 10

Cartilage
Bone
Blood
Proper

Question 11

Two types of proper tissue

Answer 11

Loose and dense

Question 12

Three types of loose tissue

Answer 12

Areolar, adipose, reticular

Question 13

Adipose

Answer 13

Fat cells, provides reserve food fuel, insulates against heat loss, under skin in hypodermis.

Question 14

Reticular

Answer 14

Network of reticular fibers in loose ground substance; form a soft internal Skelton that supports other cell types, in lymphoid organs

Question 15

Areolar

Answer 15

Gell like matrix, with all three fiber types, wraps and cushions organs, plays role in inflammation, conveys and holds tissue fluids, under epithelia.

Question 16

Types of dense tissue

Answer 16

Dense irregular
Elastic
Dense regular

Question 17

Dense regular

Answer 17

Parallel collagen fibers, few elastic fibers, fibroblasts.
Attaches muscles to bones; withstands great tensile stress when pulling.
In tendons, most ligaments

Question 18

Elastic

Answer 18

Dense reg connective tissue with elastic fibers
Allows recoil of tissue following stretching, aids passage recoil of lungs.
In walls of big arteries and certain ligaments associated with vertebral columns

Question 19

Dense irregular

Answer 19

Irregularly arranged collagen fibers; some elastic, fibroblasts
Withstands tension and gives strength
In capsules of organs of joints, dermis of the skin, digestive tract in submucosa

Question 20

Cartilage

Answer 20

Lacks nerve fibers
Flexible
Avascular
Stands up to tension and compression

Question 21

Three types of cartilage

Answer 21

Hyaline, elastic, and fibrocartilage

Question 22

Hyaline

Answer 22

Most abundant
Provides supprort
Covers up ends of long bones as articular cartilage
Amphous but firm matrix

Question 23

Elastic

Answer 23

More elastic fibers in matrix
Great flexibility
In ear
In ear and epiglottis

Question 24

Fibrocartilage

Answer 24

Less firm than hyaline and think collagen fibers
Absorbs compressive shock
In discs of knee joints, intervertebral discs, and pubic symphysis
