6. ANIMAL TISSUE A group of cells similar in structure, function, and origin is called tissues. In animals, the structure of a tissue depends on its function. An animal body is made of four different types of tissues these are the epithelial, connective, muscular, and nervous tissue. PRESENTORS

7. ANIMAL TISSUE The animal tissues are divided into epithelial, connective, muscular and nervous tissues. EPITHELIAL TISSUE

8. EPITHELIAL TISSUE The animal tissues are divided into epithelial, connective, muscular and nervous tissues. ANIMAL TISSUE

9. EPITHELIAL Epithelial tissue is a type of tissue made up of tightly packed cells commonly seen outside the body as coverings or as linings of organs and cavities.

10. EPITHELIAL The types of epithelia are classified by the shapes of cells present and the number of layers of cells. a single layer of cells is called simple epithelia a multiple layers of cells is called stratified epithelia SQUAMOUS COLUMNAR CUBOIDAL

11. TYPES OF EPITHELIAL SQUAMOUS CUBOIDAL COLUMNAR

12. EPITHELIAL TISSUE

13. SQUAMOUS Consists of flat cells, facilitating efficient diffusion; provides protective barriers, found in blood vessels and skin.

15. EPITHELIAL TISSUE

16. CUBOIDAL Cube-shaped cells involved in secretion and absorption, present in kidney tubules and glands.

17. CUBOIDAL

18. EPITHELIAL TISSUE

19. COLUMNAR Tall, column-like cells specialized for absorption and secretion, with structures like cilia or microvilli; found in the lining of the small intestine and glands.

20. COLUMNAR CONNECTIVE TISSUE

21. CONNECTIVE TISSUE

22. CONNECTIVE Connective tissues are made up of a matrix consisting of living cells and a non-living substance, called the ground substance.

23. CONNECTIVE Connective tissues are made up of a matrix consisting of living cells and a non-living substance, called the ground substance. LOOSE BLOOD BONE

24. TYPES OF CONNECTIVE LOOSE BONE BLOOD

25. CONNECTIVE TISSUE

26. LOOSE CONNECTIVE This type of connective tissue has loosely arranged fibers and cells suspended in a semi-fluid ground substance. Its main function is to absorb and bind tissues together.

27. LOOSE CONNECTIVE ADIPOSE RETICULAR AREOLAR

28. OTHER CLASSIFICAIONS OF LOOSE AREOLAR RETICULAR ADIPOSE

29. AREOLAR Present beneath the skin and serves as a support for epithelium.

30. RETICULAR Connective tissue that extends throughout your body. It is located mainly beneath the skin.

31. ADIPOSE Named for the reticular fibers which are the main structural part of the tissue.

32. CONNECTIVE TISSUE

33. BONE Bone tissue is characterized by a hard matrix composed of mineralized calcium and phosphate salts, along with collagen fibers. Bones provide support, protection for internal organs, and serve as a reservoir for minerals like calcium and phosphate. Bone marrow within bones is involved in blood cell formation.

34. BONE There are three types of cells in bone: osteoblasts osteocytes osteoclasts

35. BONE Osteoblasts are active in making bone for growth and remodeling. Osteoblasts deposit bone material into the matrix and, after the matrix surrounds them, they continue to live, but in a reduced metabolic state as osteocytes . Osteocytes are found in lacunae of the bone. Osteoclasts are active in breaking down bone for bone remodeling, and they provide access to calcium stored in tissues. Osteoclasts are usually found on the surface of the tissue.

39. BLOOD Blood is a fluid connective tissue composed of red blood cells, white blood cells, platelets, and plasma. It transports oxygen, nutrients, hormones, and waste products throughout the body. Blood is also involved in immune responses and helps regulate body temperature.

40. BLOOD AREOLAR ADIPOSE RETICULAR MUSCULAR TISSUE

41. MUSCULAR TISSUE

42. MUSCLE Muscle tissues are tissues composed of long cells called muscle fibers that allow the body to move voluntary or involuntary. Movement of muscles is a response to signals coming from nerve cells. SKELETAL CARDIAC SMOOTH

43. TYPES OF MUSCULAR SKELETAL CARDIAC SMOOTH

44. SKELETAL Striated in appearance; voluntary movements

45. CARDIAC Striated with intercalated disk for synchronized heart contraction; involuntary

46. SMOOTH Not striated muscle with tampered ends; involuntary

47. MUSCULAR TISSUE TISSUE

48. SKELETAL Skeletal connective tissue is a type of connective tissue which is composed of solid matrix and cells. It consists of bone, cartilage, tendons and ligaments. The main function of it is to provide support and protect the soft part of the body. It also gives shape and form to the body.

49. SKELETAL

50. MUSCULAR TISSUE CONNECTIVE TISSUE

51. SMOOTH Smooth muscle consists of thick and thin filaments that are not arranged into sarcomeres giving it a non-striated pattern. The main function of smooth muscle of is to mix and propel intraluminal contents to enable efficient digestion of food, progressive absorption of nutrients, and evacuation of residues.

52. SMOOTH

53. MUSCULAR TISSUE CONNECTIVE TISSUE

54. CARDIAC Cardiac muscle is highly organized and contains many types of cell, including fibroblasts, smooth muscle cells, and cardiomyocytes. Cardiac muscle only exists in the heart. It contains cardiac muscle cells, which perform highly coordinated actions that keep the heart pumping and blood circulating throughout the body.

55. CARDIAC NERVOUS TISSUE

56. NERVOUS TISSUE MUSCULAR TISSUE

57. NERVOUS Nervous tissues are composed of nerve cells called neurons and glial cells that function as support cells. These neurons sense stimuli and transmit electrical signals throughout the animal body. NERVE CELLS GLIAL CELLS

58. TYPES OF NERVOUS NERVE CELLS GLIAL CELLS

59. NERVOUS TISSUE MUSCULAR TISSUE

60. NERVE CELLS Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.

62. NERVOUS TISSUE MUSCULAR TISSUE

63. GLIAL CELLS Many glial cells provide support for an essential nervous system function. In addition to providing support for neurons, glial cells aid in the maintenance of homeostasis, and form myelin. As a whole, glial cells are the most abundant cells in the central nervous system.
