Anatomy Notes Class 1

Front 1

skin( top layer down)

Back 1

epidermis-dermis- arrector pili muscle- sweat gland- hair follice- blood vessels

Front 2

Bone

Back 2

Is a tissue with a solid feel

Front 3

Muscle

Back 3

moves the skeleton made up of muscle cells, layers of connective tissue(fascia) and numerous nerves and blood vessels, muscle tissue has a striated texture- unique because it can be in a contracted or relaxed state

Front 4

Perimysium

Back 4

A bundle of fibers enveloping each fascicle

Front 5

Tendon

Back 5

Tendon's are dense connective tissue in a bundle of parallel collagen fibers. They attach muscle to the periosteum (connective tissue that surrounds the bone), essentially tendons attach muscle to the bone.

Front 6

Ligament

Back 6

Ligaments are an uneven configuration of dense connective tissue that connects bones together

Front 7

Difference between tendon and ligament?

Back 7

tendon connects muscle to bone and has a parallel makeup while ligaments connect bone to bone and has an uneven structure

Front 8

Fascia

Back 8

Like tendons and ligaments fascia form a dense connective tissue but it is a continuous sheet of fibrous membrane that is beneath the skin and around muscles and organs

Front 9

Artery and Vein

Back 9

Arteries are on the protected side of the appendage buried deep in the musculature, while veins are easily palpated and don't have a pulse .

Front 10

Bursa

Back 10

A bursa is a small fluid filled sack that reduces friction between two structures stiuated mainly around joints

Front 11

Nerve

Back 11

Nerve vessels are tube shaped mobile and tender when compressed. if compressed or impinged the nerve may create sharp shooting sensation down the appendage

Front 12

Lymph Node

Back 12

lymph nodes collect lymphatic fluid from lymphatic vessels. They are bean shaped and may range in sin from tiny pea to almond. they are located throughout the body, they are glands that are smaller than other glans and have irregular lumpy surfaces

Front 13

Adipose Tissue

Back 13

Adipose tissue is a form of loose connective tissue. it is in many levels throughout the body including marrow of long bones and around kidneys

Front 14

Planes of movement

Back 14

sagittal plane, frontal or coronal plane, and transverse plane

Front 15

sagittal plane

Back 15

divides body into left and right halves

Front 16

Frontal (coronal) plane

Back 16

divides body into front and back portions

Front 17

Transverse plane

Back 17

dividing the body into upper and lower parts

Front 18

Circumduction

Back 18

only at the shoulder and hip joints. It is the combination of flexion, extension, adduction and abduction

Front 19

Prone

Back 19

is the position of lying on the table face down

Front 20

Supine

Back 20

(on your spine) is to lie face up

Front 21

sidelying

Back 21

to lie on your side

Front 22

lateral flexion

Back 22

occurs only at the axial skeleton, when the head or vertebral column bend laterally to the side

Front 23

supination and pronation

Back 23

refer to pivoting action of forearm, supination- carrying a bowl, while pronation is spilling the bowl, palm facing the floor

Front 24

Opposition

Back 24

happens only at the carpometacarpal joint of the thumb occurs when the thumbpad crosses the palm toward the pinky finger

Front 25

Inversion and Eversion

Back 25

inversion turns in the foot, so the sole of the foot is medial, eversion- turns out - the foot where the sole of the foot is lateral

Front 26

plantar flexion

Back 26

point foot toward earth

Front 27

dorsiflexion

Back 27

taking foot off gas pedal

Front 28

SITS muscles

Back 28

the rotator cuff muscles
supraspinatus, infraspinatus, teres minor, subscapularis

Front 29

How many muscles are in the body?

Back 29

630

Front 30

Only humans have..

Back 30

opposable thumbs

Front 31

adduction

Back 31

add to the body

Front 32

abduction

Back 32

moving away from the body

Front 33

retinaculum

Back 33

a structure that retains an organ or tissue in place.

Front 34

bipennate

Back 34

Of or relating to a muscle with a central tendon toward which the fibers converge on either side like the barbs of a feather.

Front 35

collagen

Back 35

any of a family of extracellular, closely related proteins occurring as a major component of connective tissue, giving it strength and flexibility

Front 36

Superior

Back 36

refers to a structure closer to the head

Back 40

concerns a structure further toward the back of the body than another structure

Front 41

Anterior
