A thick yellow connective-tissue fiber composed principally of elastin and characterized by great elasticity.

Question 28

Cartilage

Answer 28

Cartilage /ˈkɑrtɨlɨdʒ/ is a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the bronchial tubes and the intervertebral discs. It is not as hard and rigid as bone but is stiffer and less flexible than muscle.

Question 29

Chondrocytes

Answer 29

Chondrocytes (from Greek chondros cartilage + kytos cell) are the only cells found in healthy cartilage.

Question 30

Hyaline Cartilage

Answer 30

Hyaline cartilage is a type of cartilage found on many joint surfaces. It is pearly bluish in color with firm consistency and considerable collagen. It contains no nerves or blood vessels, and its structure is relatively simple.

Question 31

Elastic Cartilage

Answer 31

Elastic cartilage or yellow cartilage is a type of cartilage present in the outer ear, Eustachian tube and epiglottis. It contains elastic fiber networks and collagen fibers. The principal protein is elastin.

Question 32

Fibrocartilage

Answer 32

White fibrocartilage consists of a mixture of white fibrous tissue and cartilaginous tissue in various proportions. It owes its flexibility and toughness to the former of these constituents, and its elasticity to the latter. It is the only type of cartilage that contains type I collagen in addition to the normal type II.

Question 33

Bone

Answer 33

Bones are rigid organs that constitute part of the endoskeleton of vertebrates. They support and protect the various organs of the body, produce red and white blood cells and store minerals.

Question 34

Osteocytes

Answer 34

An osteocyte, a star shaped cell, is the most commonly found cell in mature bone, and can live as long as the organism itself.

Question 35

Osteon

Answer 35

The osteon or Haversian system /həˈvɜr.ʒən/ is the fundamental functional unit of compact bone. Osteons are roughly cylindrical structures that are typically several millimeters long and around 0.2mm in diameter.

Question 36

Caniculi

Answer 36

Bone canaliculi are microscopic canals between the lacunae of ossified bone. The radiating processes of the osteocytes project into these canals. These cytoplasmic processes are joined together by gap junctions. Osteocytes do not entirely fill up the canaliculi. The remaining space is known as the periosteocytic space, which is filled with periosteocytic fluid. This fluid contains substances too large to be transported through the gap junctions that connect the osteocytes, including calcium and phosphate ions.

Question 37

Blood

Answer 37

A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs).

Question 38

Hematopoietic tissues

Answer 38

Hematopoietic stem cells (HSCs) are the blood cells that give rise to all the other blood cells.

Question 39

Skeletal muscle tissue

Answer 39

Muscle tissue is one of four basic biological tissues present in animals. It is a soft tissue that composes muscles. It is formed during embryo development in a process known as myogenesis.

Question 40

Smooth muscle tissue

Answer 40

Smooth muscle is an involuntary non-striated muscle. It is divided into two sub-groups; the single-unit (unitary) and multiunit smooth muscle.

Question 41

Cardiac muscle tissue

Answer 41

Cardiac muscle (heart muscle) is a type of involuntary striated muscle found in the walls and histological foundation of the heart, specifically the myocardium.

Question 42

Nervous tissue

Answer 42

Nervous tissue is the main component of the nervous system – the brain, spinal cord, and branching peripheral nerves – which regulates and controls bodily functions. It is composed of neurons, which transmit impulses, and neuroglia cells, more commonly called glia,(from the Greek, meaning glue) which assist the propagation of the nerve impulse as well as providing nutrients to the neuron.

Question 43

Neurons

Answer 43

A neuron (/ˈnjʊərɒn/ nyewr-on or /ˈnʊərɒn/ newr-on; also known as a neurone or nerve cell) is an electrically excitable cell that processes and transmits information through electrical and chemical signals.

Question 44

Neurological cells

Answer 44

Neuroglial cells—usually referred to simply as glial cells or glia—are quite different from nerve cells. The major distinction is that glia do not participate directly in synaptic interactions and electrical signaling, although their supportive functions help define synaptic contacts and maintain the signaling abilities of neurons.

Question 45

Epithelial membranes

Answer 45

Epithelium is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue.

Question 46

Synovial membranes

Answer 46

Synovial membrane (also known as synovium or stratum synoviale) is the soft tissue found between the articular capsule (joint capsule) and the joint cavity of synovial joints.

Question 47

Serous membrane

Answer 47

In anatomy, serous membrane (or serosa) is a smooth membrane consisting of a thin layer of cells which secrete serous fluid, and a thin epithelial layer.

Question 48

Mucous membrane

Answer 48
