lecture day 3 connective, muscle, and nervous tissue

What are the main functions of connective tissues?

Binding, support, protection, movement, storage, and transport.

What type of connective tissue is responsible for binding tendons and ligaments?

Connective tissue proper.

What is the role of fibroblasts in connective tissue?

Fibroblasts produce fibers and the matrix (ground substance).

What type of cells are macrophages?

Phagocytes that engulf and break down substances.

What is the main function of adipocytes in connective tissue?

Adipocytes store lipids.

What are collagen fibers known for?

Being flexible, stronger than steel, and thick.

What type of connective tissue provides structure and support to organs like the liver and spleen?

Reticular tissue.

What is the main difference between dense regular and dense irregular connective tissue?

Dense regular connective tissue has fibers going the same direction, while dense irregular has fibers in multiple directions.

What does hyaline cartilage provide?

Support and flexibility, found in structures like nasal cartilage.

What are the three types of muscle tissue?

Skeletal, cardiac, and smooth.

What is the function of neurons?

To make electrical impulses that communicate between cells.

What is the purpose of neuroglial cells?

To maintain the nervous system.

What type of membrane lines body cavities and includes goblet cells?

Mucous membrane.

What characterizes cutaneous membranes?

They are mostly dry and water-resistant, with stratified squamous epithelium.

What is the key difference between blood and lymph in fluid connective tissue?

Blood contains erythrocytes, leukocytes, and thrombocytes; lymph regulates blood volume and supports the immune system.

What is the primary function of smooth muscle tissue?

To assist in moving blood through blood vessels involuntarily.

What type of cartilage has a high abundance of elastic fibers?

Elastic cartilage, found in structures like the ear.

What do mast cells release to increase blood flow?

Histamine.

What are the vascular components of bone?

Collagen fibers, calcium salts, and calcium phosphate.

What type of connective tissue is adipose tissue classified as?

Loose connective tissue.
