• What tissues consist of ELONGATED CELLS?

  Muscle tissues
• Muscle tissues composed of cells that optimize which universal cell property?

  Contractility
• What type of tissue is responsible for the movement of the body?

  Muscle tissue
• What is the functional unit of muscle tissue?

  Sarcomere
• LABEL:

  A) NUCLEI

  B) STRIATIONS

  C) MUSCLE FIBER

  D) CONNECTIVE TISSUE

  
• LABEL:

  A) BRANCHING

  B) STRIATIONS

  C) INTERCALATED DISC

  D) NUCLEUS

  E) GLYCOGEN

  
• LABEL:

  A) NUCLEI

  B) MUSCLE CELLS

  
• WHAT IS THIS?

  SMOOTH MUSCLE

  
• WHAT IS THIS?

  SKELETAL MUSCLE

  
• WHAT IS THIS?

  CARDIAC MUSCLE

  
• Skeletal muscle: bundles of VERY LONG, MULTINUCLEATED cells with STRIATIONS
• Describe the contraction of skeletal muscle?

  Quick and Forceful
• Is the skeletal muscle a voluntary or involuntary muscle?

  voluntary
• Why is the skeletal muscle multinucleated?

  due to its long MORPHOLOGY
• Skeletal muscle is prone to what?

  Fatigue
• Skeletal muscle is subjected into what?

  Training
• What are the 3 layers of skeletal muscle?

  Epimysium, perimysium, and endomysium
• EPIMYSIUM: Surrounds the WHOLE MUSCLE
• PERIMYSIUM: Surrounds the FASCICLES of bundles
• ENDOMYSIUM: surrounds the INDIVIDUAL MUSCLE FIBER
• LABEL:

  A) EPIMYSIUM

  B) PERIMYSIUM

  C) ENDOMYSIUM

  
• LABEL:

  A) PERIMYSIUM

  B) ENDOMYSIUM

  
• What time of muscle tissue is attached to the BONE?

  Skeletal muscle
• Skeletal muscle is responsible for movement of the AXIAL and APPENDICULAR skeleton for maintenance of body POSITION and body POSTURE.
• Cardiac muscle: has CROSS-STRIATIONS and composed of elongated, often BRANCHED cells bound to one another at structures called INTERCALATED DISC (gap junctions).
• Describe the contraction of CARDIAC MUSCLES?

  Vigorous and Rhythmic
• Is the cardiac muscle voluntary or involuntary muscle?

  Involuntary
• LABEL:

  A) CROSS-STRIATIONS

  B) INTERCALATED DISC

  C) INTERCALATED DISC

  D) ENDOMYSIUM

  E) CAPILLARY

  F) CENTRAL NUCLEUS

  
• Cardiac muscle is located in the wall of the HEART and in the BASE of LARGE VEINS that empty into the heart.
• Smooth muscle consists of collections of FUSIFORM CELLS and LACK STRIATIONS.
• Describe the contraction of smooth muscle?

  Slow and involuntary
• Smooth muscles are seen in which type of organ?

  hollow organs
• Give examples of hollow organs?

  digestive system and blood vessels
• What is this?

  Smooth muscle

  
• Smooth muscles are also found in the VISCERA and VASCULAR SYSTEM containing blood vessels, the ARRECTOR PILI muscles of the skin, and the INTRINSIC MUSCLE of the eye.
• Are cross-striations present in smooth muscle cells?

  no
• MYOFILAMENTS do not achieve the same degree of order of management.
