Epithelial tissue - --Answers---Covers all body surfaces; lines
all cavities; forms glands; Protective barrier against the
environment
What are the major organ systems - --Answers---
Integumentary, Skeletal, Muscular, Circulatory, Lymphatic,
Respiratory, Digestive, Urinary, Reproductive, Nervous,
Endocrine
Integumentary System - --Answers---The skin, or integument,
covers an animal and protects it for the outside environment
Vertebrate skin has three basic structures. What are they? - --
Answers---Epidermis, Dermis, Glands
Skeletal System - --Answers---A skeleton is the framework of
an animal's body; Most vertebrates have an internal skeleton or
endoskeleton, which protects various parts of the body; The
skeleton facilitates movement.
What are the two tissue types in the vertebrate skeleton? - --
Answers---Bone and Cartilage
,What are the 4 types of bones classified by shape? - --Answers-
--Long bones (diaphysis), short bones (epiphysis), Flat bones
(medullary cavity), irregular bones (periosteum)
What are the 2 main bone groups? - --Answers---Axial skeleton
and appendicular skeleton
Axial Skeleton - --Answers---Skull -Two parts: cranium and
facial; Vertebrae -Vertebral column consists of bones known as
vertebrate; Ribs and sternum; Part of the thoracic region
Appendicular Skeleton is made up of... - --Answers---bones and
includes the pectoral girdle
The forelimb consists of the: - --Answers---Humerus (upper
arm), Radius and ulna (forearm), Carpals (wrist bones),
Metacarpals (hand bones), Phalanges (fingers, digits, thumbs)
The hindlimb consists of the: - --Answers---Femur (thigh),
Tarsals (ankle bones), Metatarsals (foot bones), Patella (knee
cap), Tibia and fibula (lower leg), Phalanges (toes)
What words are used to describe joint movement? - --Answers-
--Rotation, Flexion, Extension, Abduction, Adduction
,Rotation - --Answers---Pivot movement; e.g., turning the head,
Flexion - --Answers---Bending or folding; e.g., elbow joint
Extension - --Answers---Opening the joint
Abduction - --Answers---Movement of bone away from midline
Adduction - --Answers---Movement toward the midline
Muscular System - --Answers---Muscle tissue found in almost
every part of the body and consists of three distinct types:
Skeletal muscle, Smooth muscle, and Cardiac muscle
What is the function of Skeletal muscle (striated muscle)? - --
Answers---Primary function is movement of bones
What are the functions of smooth muscle? - --Answers---
Muscle contractions are involuntary, Walls of blood vessels and
organs of digestive system
What are the functions of cardiac muscle? - --Answers---
Specialized type of striated muscle; Normally self-stimulating,
producing the continuous pumping of the heart
, What is the primary function of the circulatory system? - --
Answers---Primary function of circulatory system is to remove
carbon dioxide and waste products from cells.
What does the circulatory use in order to function? - --Answers-
--The medium transport is blood. Blood is composed of a plasma
portion and several types of cellular elements. Plasma
comprises 55 percent of total blood volume.
Erythrocytes are - --Answers---most abundant type of blood
cell.
Where is erythrocytes produced? - --Answers---Produced
primarily in the bone marrow and aids the transport of
respiratory gases
What are Leukocytes and what are the 2 main types? - --
Answers---Less abundant than RBCs, Granulocytes and
Lymphoid cells
What are granulocytes and how are they classified? - --
Answers---Relatively large cells; nuclei are multi-lobed;
cytoplasm contains microscopic granules; Classified based on
straining properties:
