Tissue groups (5)

A
  1. skin
  2. fascia
  3. muscle
  4. bone
  5. fat
18
Q

Skin

A

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

19
Q

Fascia

A

(specializations include the superficial and deep layers)

20
Q

Muscle

A

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

21
Q

Bone

A

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

22
Q

Fat

A

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

23
Q

Smooth muscle tissue

A

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
Q

Cardiac muscle tissue

A

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
Q

Skeletal muscle tissue

A

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
