The shaft or body is the long middle part of the ulna bone. Medical Definition of Epidermis. Biology is the branch of science concerned with the study of life: structure, growth, functioning, and evolution of living things. Dialysis: The process of removing waste products and excess fluid from the body. Dialysis is necessary when the kidneys are not able to adequately filter the blood. It is primarily made of dead, keratinized cells. The scrotum is a sac of skin that contains several important parts of the male reproductive system. Hair abnormalities are common in RHS. To explain torque in detail let us consider the figure. There are two types of dialysis: hemodialysis and peritoneal dialysis. Matching game, word search puzzle, and hangman also available. Dialysis allows patients with kidney failure a chance to live productive lives. The deepest part of the epidermis also contains melanocytes. Definition: Synovial Term: The function of a bursa is? The filament supports the anther, which is where pollen develops. A female homologue of the male penis, the clitoris develops (as does the penis) from the genital tubercle of the fetus, and it plays an important role in female sexual response. 1. the portion of a long bone between the ends or extremities, which is usually articular, and wider than the shaft; it consists of a tube of compact bone, enclosing the medullary cavity. Penis, the copulatory organ of the male of higher vertebrates that in mammals usually also provides the channel by which urine leaves the body. something directed or barbed as in sharp attack: shafts of sarcasm. Definition: Any underground gallery or passage through which a portion of the ventilation passes, that is, the air is carried. Two Types of Induction MotorsSingle phase induction motor: The single-phase induction motor is not self-starting. It is also called a bioreactor, as it makes the use of microbial biomass to accomplish the fermentation process. Shaft. When the motor is connected to a single-phase power supply, the main winding carries an alternating current. Zoology A small, sharp point projecting in reverse direction from the tip, as on a porcupine quill or a bee sting. Induction Motor: Working Principle, Types, & Definition. Medical Author: William C. Shiel Jr., MD, FACP, FACR; Epidermis: The upper or outer layer of the two main layers of cells that make up the skin. Strands of hair originate in an epidermal penetration of the dermis called the hair follicle.The hair shaft is the part of the hair not anchored to the follicle, and much of this is exposed at the skin’s surface. Journal of Experimental Biology 2014 217: 1656-1666; doi: 10.1242/jeb.097097 , , , , , , ... NC, USA) was attached to the cylindrical shaft and allowed for three forces (F x, F y, F z) and three torques (T x, T y, T z) to be measured simultaneously. The inner sheath follows the hair shaft and ends just before the opening of the sebaceous gland. The skeletal system provides support and protection for the body’s internal organs and gives the muscles a point of attachment. Clitoris, female erogenous organ capable of erection under sexual stimulation. Hair color can be white, hypopigmented, blonde or light, and hair shaft abnormalities can include pili torti and pili canaliculi ( Park et al., 2005 ). Many agree that it is also the strongest (the jaw bone is the other contender). This preview shows page 11 - 17 out of 36 pages.. What joint is most moveable? The corresponding structure in lower invertebrates is often called the cirrus. 3. *Response times vary by subject and question complexity.

Typically, the hair shaft consists of three layers: an external cuticle made up of overlapping microscopic scales, the middle cortex containing shriveled cells and pigments, and an inner medulla containing air spaces in larger hairs. The skeleton is the supporting framework of an organism.It is typically made out of hard, rigid tissue that supports the form of the animal’s body and protects vulnerable organs.. For land-dwelling animals, skeletons are also necessary to support movement, since walking and flying rely on the ability to exert force on rigid levers such as legs and wings. cells surrounding stomata that, through osmosis, regulate the openings and closings of the stomata. It's attached to several other bones. Air shaft. Definition: Provide a fluid filled cushion that Provide a … Interlocking barbules are clearly seen in the middle image. 2. Under the squamous cells are round cells called basal cells. The drive shaft in a racing car accelerating from the start line exhibits dynamic torque because it must be producing an angular acceleration of the wheels, given that the car is accelerating along the track. barb 1 (bärb) n. 1. The two femur bones serve as pillars in our legs that allow us to walk, run, jump, and make all kinds of other movements. Centrifugal force definition. Anterior region of a contour feather from a rock pigeon, visualized using scanning electron microscopy. long bone - bone that is longer than wide, and has a shaft and two ends See illustration. Hence, the body is in translational equilibrium. The outer sheath continues all the way up to the sebaceous gland. Definition. Foils were attached to the force transducer via a stainless steel clamp and submerged at mid-depth in the water tank. blade. guard cells. Hollow shaft, calamus; Feather structure of a blue-and-yellow macaw. A cutting remark. When the muscle contracts, it causes the hair to stand up, otherwise known as goosebumps. Median response time is 34 minutes and may be longer for new subjects. Specifically, hair may be coarse, woolly, thin, short, wiry, curly, dry, sparse, straw-like, or brittle.
