Skeletal Muscle

Function: Skeletal muscle represents the majority of muscle tissue. It is the type of muscle that powers movement of the skeleton, as in walking and lifting.

Location: Attached to bones

Structure: Striated, multiple nuclei per cell, very long cylindrical shape.

Striated Muscle

A muscle that is connected at either or both ends to a bone and helps move parts of the skeleton; a muscle that is characterized by transverse stripes.

Also known as Skeletal muscle.

Elastic Cartilage

Function: Elastic cartilages provides support to surrounding structures and helps the define and maintain the shape of the area in which it is present, e.g. the external ear.

Location: Auditory (Eustachian) Tubes; External Ear (Auricle); Epiglottis (the lid on the top of the larynx).

Structure: In elastic cartilage, which is yellowish in color, the cartilage cells (chondrocytes) are located in a threadlike network of elastic fibres within the matrix of the cartilage. A perichondrium is present.

Compact Bone 

Function: Weight bearing, weight transfer, protection, site for muscle attachment.

Location: Makes up 80% of the human skeleton and forms the outer layer of all bones.

Structure: Is lamellar, or layered, in structure. It is permeated by an elaborate system of interconnecting vascular canals.The bone is arranged in concentric layers around those canals, forming structural units called osteons.

Spongy Bone

Function:  Is the tissue that makes up the interior of bones. Spongy bone tissue is light and supports and protects the red bone marrow.  It is very important for producing blood cells.

Location: Interior of bones; It is found in the ends of long bones and in the bones of the pelvis, ribs, vertebrae, and skull.

Structure: Is a network of irregularly-shaped sheets and spikes of bone (trabeculae). The trabeculae are only a few cell layers thick. It is spongy and porous and is filled with red bone marrow.

Hyaline Cartilage

Function: Supports and reinforces; has cushioning properties; resists compressive stress.

Location: Forms most of the embryonic skeleton; covers the ends of long bones in joint cavities; forms costal cartilages of the ribs; cartilages of the nose, trachea, and larynx. Covering the surface of bones at joints - especially in areas where damage due to wear may lead to osteoarthritis incl. e.g. the ends of the long bones, and also the anterior ends of the ribs.

Structure: Consists of elastic material with a matrix of chondroitin sulphate into which many fine collagen fibrils are embedded. It contains numerous chondrocytes.

Compound Eye

Arthropod eyes are called compound eyes because they are made up of repeating units, the ommatidia, each of which functions as a separate visual receptor.

Ovaries

Function: Are the female gonads, or sex cell-producing organs, which produce eggs, or ova. They are very important in the overall reproductive functions of the female body.

Location: They are located at the ends of the uterine tubes, which are connection tubes that attach to the uterus.

Structure: The ovaries are roughly four cubic centimeters in size, which is about the size of a walnut.

Testes

Function: They are the most essential organs of the male reproductive system. They are the glands where sperm and testosterone are produced.

Location: The testes are contained in the scrotum.

Structure: They are composed of dense connective tissue containing around three hundred internal compartments called lobules. Each of these lobules contains a number of coiled, tiny tubules where the sperm are produced. Testosterone is produced in cells located in between the lobules.
