Tissue Aggregates

Question 1

Tissue Aggregates

Answer 1

Elementary tissues are combined to form larger structures

Question 2

Fascia

Answer 2

sheet like membrane around organs. When it is around muscles it is called Perimysium.

Question 3

Ligaments

Answer 3

binding together two structures.

Visceral ligaments: hold organs in place

skeletal ligaments: connect bones to bones

Question 4

Tendons

Answer 4

attach muscle to bone or cartilage. Parallel fibers. sometimes take on shape of muscles they connect to.

Sheet like tendon is called Aponeurosis.

Question 5

bones

Answer 5

provide rigid support for the body. protect organs and soft tissues.

outer layer - periosteum

bones start out as cartilage and gradually ossify during childhood.

Question 6

Joints

Answer 6

Connect bone to bone or cartilage to cartilage. Classified based on the degree of movement.

Question 7

Diarthrodial joints

Answer 7

permit maximum mobility

Question 8

Amphiarthrodial joints

Answer 8

permit limited mobility

Question 9

Synarthrodial joints

Answer 9

permit no mobility. fibrous.

Question 10

Suture Joints

Answer 10

Fibrous Joints between bones of a skull not intended to move.

Question 11

Gomphosis joints

Answer 11

Fibrous joint in which a peg fits into a hole. Teeth for example.

Question 12

Muscles

Answer 12

Bound groups of muscle fibers with anatomic utility.

covered by fascia

Have blood supply to support metabolic activity/remove waste

Have neural supply: efferent, afferent

Question 13

Efferent

Answer 13

motor fibers that signal muscle contraction

Question 14

Afferent

Answer 14

Sensory fibers that indicate status of muscle to nervous system

Question 15

What are the 6 types of tissue aggregates?

Answer 15

Fascia

Ligaments

tendons

bones

joints

muscles

Question 16

agonist

Answer 16

muscle contracted for purpose of a specific motor act - moving together

Question 17

antagonist

Answer 17

muscle that opposes the contraction of another muscle - moving apart

Question 18

synergist

Answer 18

muscle that assists the agonist accomplishing the movement

Question 19

Muscle Innervation

Answer 19

stimulation of a muscle by means of a nerve: Afferent, Efferent

Question 20

Afferent Innervation

Answer 20

sensory - information is being carried towards a central location.

Question 21

Efferent Innervation

Answer 21

excitatory - information is being carried away from a central point.
