This region in sarcomere is occupied primarily by the thick myofilament.

This region in a sarcomere is occupied by the protein Myomesin.

This region in a myofibril from one Z-line to another Z-line is the smallest contractile unit of skeletal & cardiac muscle tissue

The smooth endoplasmic reticulum of skeletal and cardiac muscle tissue has this specialized name

These multipotent cells are found in connective tissue of the umbilical cord

In connective tissue proper found in adults, these are the active cells that synthesizes the precursor for collagen fibers, as well as the components of the extracellular matrix.

These fixed cells of the connective tissue are filled with secretory granules that almost obscures the nucleus of the cells. These granules in turn contains molecules that are involved in allergic reactions.

The following are wandering cells of the connective tissue, except:

This region in a sarcomere is occupied primarily by the thin myofilament

These cells differentiate from B-lymphocytes and are responsible for the production of antibodies.

• Resident Cells (Fixed)

• Visiting Cells (Wandering)

promotes smooth muscle contraction à increase vascular permeability

This type of connective tissue fiber forms networks or meshwork of thin fibers and are mostly found in stroma of organs

Which among the following is the major protein found in elastic fibers?

A proteoglycan is made up of a core protein attached to which are many:

This is the most abundant type of connective tissue in the body.

This layer of the dermis is made of dense irregular connective tissue

The connective tissue beneath the simple columnar epithelium lining the sma intestine is called the lamina propria. The connective tissue found here is:

Surrounding the blood vessels in the umbilical cord is a jelly-like substance called the Wharton's jelly. It is made up of:

The most abundant fiber in this connective tissue are reticular fibers.

The cells of bone and cartilage are housed in a cavity called the

The following are characteristics of cartilage tissue, except:

This layer of the perichondrium is lined by chondroblasts:

The following are locations where hyaline cartilage can be found, except:t

This type of cartilage appears yellowish in fresh tissue and is found in auricle of the ears, and epiglottis. The matrix of this cartilage contains elastic fibers.

This glycoprotein attaches calcium to the collagen fibers in the bone matrix.

The following bone cells originate from mesenchymal cells, except:

This layer of the cerebral cortex contains the largest pyramidal neurons in the CNS

The formation of the neural tube, also known as neurulation, commences at

• Embryonic, multipotent cells

• Rarely present in adults; if present, found in bone marrow & CT near capillaries

• “True” CT cells

• Synthesizes: collagen, reticular, and elastic connective tissue fibers; glycosaminoglycans, proteoglycans, and adhesive glycoproteins of ground substance

• Abundant in reticular tissue

• Fibroblasts that are specialized to synthesize Type III collagen

• Store fat (lipid) as a single large droplet; nuclei pushed to the side (“signet ring”)

when a fat cell is only starting to accumulate fat → Function: insulation, fat pads for organ protection

hormone that increases lipid metabolism and regulates appetite and food intake

• Cells smaller than white adipose cells; store fat as multiple lipid droplets (multilocular)

• Found in hibernating animals & newborn individuals – generates body heat

• As an adaptation to cold environment, cell numbers and tissue increase

local inflammatory response, tissue repair, innate immunity

» Antibody-producing cells

» Life span: 10-20 days

» Differentiates from B-lymphocytes

» Numerous in CT that are readily accessible to foreign proteins and bacteria such as the lamina propria of the digestive tract

nucleated cells in the blood; perform their functions in connective tissues then undergo apoptosis
