tissue that contains reticular fibers and reticular cells and forms the stroma of certain organs such as the spleen

Reticular CT

a loose connective tissue specialized for triglyceride storage

Adipose Tissue

All of the following statements are true regarding wound healing EXCEPT which of the following? A. new blood vessels form to carry oxygen and nutrients to the site in cases of wounds that extend deep into the dermis B. the primary cell that helps repair the dermal layer is the keratinocyte C. the basal layer of the epidermis seals the wound at its outermost region D. scar tissue forms at the site of the dermal injury providing strength but often lacking flexibility

All are true!!

connective tissue consisting of several kinds of cells, containing all three fiber types randomly arranged, and found in the subcutaneous layer deep to the skin

Areolar CT

tissue that forms the internal framework of the body and works with skeletal muscle to generate movement

Bone

connective tissue with formed elements suspended in a liquid matrix called plasma

Blood

Which of the following statements is true regarding cartilage? A. the most widely distributed type of cartilage is fibrocartilage used to provide strength B. the most common location of elastic cartilage is at the ends of long bones as they need to recoil from the forces of gravity during weight bearing C. hyaline cartilage is formed by chondroblasts and covers the end of long bones and many structures of the respiratory tract D. the intervertebral disk is formed predominantly by hyaline cartilage

C. hyaline cartilage is formed by chondroblasts and covers the end of long bones and many structures of the respiratory tract

Which of the following is NOT true regarding connective tissue types? A. reticular connective tissue is most suited for areas of the body which require support of delicate structures such as small blood vessels B. dense irregular connective tissue is most suited in areas that require great strength and flexibility C. loose areolar connective is widely distributed in body as it contains all types of connective tissue fibers for strength, elasticity, and support D. dense irregular tissue is primarily associated with areas that need a great deal of strength such as tendons and ligaments

D. dense irregular tissue is primarily associated with areas that need a great deal of strength such as tendons and ligaments

tissue with irregularly arranged collagen fibers found in the dermis of the skin

Dense Irregular CT

bundles of collagen arranged in parallel patterns; compose tendon and ligaments

Dense Regular CT

The joint capsule is composed of what?

Dense irregular connective tissue

tissue found in the lungs that is strong and can recoil back to its original shape after being stretched

Elastic CT

tissue that contains a network of eleastic fibers, providing strength, elasticity, and maintenance of shape; located in the external ear

Elastic Cartilage

The most abundant cell in connective tissue that is responsible to laying down the connective tissue matrix and fibers is which of the following?

Fibroblast

What is the basic cell of loose areolar connective tissue?

Fibroblast

What cartilage is found in intervertebral disc?

Fibrocartilage

tissue that provides strength and rigidity and is the strongest of the three types of cartilage

Fibrocartilage

What is the most abundant type of cartilage?

Hyaline Cartilage

What type of cartilage is found in articular cartilage at ends of bones?

Hyaline Cartilage

tissue that affords flexibility at joints and reduces joint friction

Hyaline Cartilage

connective tissue with a clear, liquid matri that flows in lymphatic vessels

Lymph

the tissue from which all other connective tissue eventually arises

Mesenchyme

In the repair process of skin and bone, the process by which nutrients and oxygen are supplied to fibroblasts and osteoblasts is called:

angiogenesis

The matrix of connective tissue consists of ground substance in which float fibers and cells. The ground substance has two major components. One of the components is glycosaminoglycans (GAGs). An example of a GAG is ________________________.

hyaluronic acid, dermatan sulfate, chondroitin sulfate, kerratan sulfate

The GAGs are associated with a protein in a precise structural arrangement (brush handle with bristles). This protein is a _______________________.

proteoglycan

Cartilage tissues are likely to be slow in healing following an injury because:

they lack direct blood supplies
