Flashcards in Unit 1: Lecture 1 Self-study Deck (25):
1

Plane of reference: Median (midsagittal)

divides the body into right/left halves

2

Plane of reference: Frontal (coronal)

divides the body into anterior/ posterior portions

3

Plane of reference: Transverse (horizontal)

divides the body into upper/ lower portions

4

Superior (cephalad) //

Inferior (caudad)

5

Anterior (ventral) //

Posterior (dorsal)

6

Medial //

Lateral

7

Superficial //

Deep

8

Proximal //

Distal

9

Supine //

Prone

10

Extension

reduces degree of acute joint angulation

11

Flexion

produces an acute angle at a joint

12

Abduction

moves away from the body

13

Adduction

moves towards the body

14

Circumduction

combination of extension, flexion, abduction, and adduction

15

Elevation //

Depression

16

Protraction //

Retraction

17

Tissue groups (5)

1. skin
2. fascia
3. muscle
4. bone
5. fat

18

Skin

covers the body externally and has three layers (epidermis, dermis, hypodermis)

19

Fascia

(specializations include the superficial and deep layers)

20

Muscle

note organization from slide views and consists of skeletal, smooth, and cardiac divisions

21

Bone

skeleton consists of an axial skeleton (skull, spine, and thorax) and an appendicular skeleton (upper/ lower limbs)

22

Fat

(panniculus adiposis or hypodermis). The panniculus adiposis along with its underlying superficial membranous fascia are referred to as tela subcutanea.

23

Smooth muscle tissue

Location: mostly in walls of hollow visceral organs

Cell shape and appearance: single, fusiform, uninucleate; NO striations

Connective tissue components: endomysium

Contractions: involuntary, controlled by nervous system, and very slow

24

Cardiac muscle tissue

Location: walls of the heart

Cell shape and appearance: branching chains of cells; uninucleate, striations; intercalated discs

Connective tissue components: endomysium attached to the fibrous skeleton of the heart

Contractions: involuntary, heart as pacemaker, also controlled by nervous system, and slow

25

Skeletal muscle tissue

Location: attached to bones or skin (some facial muscles)

Cell shape and appearance: single, very long, cylindrical, multinucleate with very obvious striations

Connective tissue components: epimysium, perimysium, and endomysium

Contractions: voluntary, nervous system controls, and slow to fast
