Structural Organisation in Animals

Epithelial Tissue

Tissues that form a covering or lining for most of internal organs and body surfaces, classified based on cell layers and shapes into squamous, cuboidal, columnar, and ciliated types.

Connective Tissue

The most abundant and widely distributed tissue in complex animals, responsible for linking and supporting other tissues/organs, including blood, bone, cartilage, and adipose tissue.

Muscle Tissue

Specialized tissues composed of elongated cells called muscle fibers that contract and relax to cause movement, divided into skeletal, smooth, and cardiac muscles.

Nervous Tissue

Tissue comprised of neurons and neuroglial cells that exert the greatest control over the body's responsiveness to changing conditions through electrical impulses.

Cockroach Anatomy

Study of the morphological and anatomical systems of Periplaneta americana, including its digestive, circulatory, respiratory, nervous, and reproductive systems.
