2 Structure and function 2.1 Structure and function of the outer and middle ear. Figure 1 is a diagram of the human ear. The outer ear consists of the visible part of the ear or pinna, the external auditory canal (meatus) , and the tympanic membrane (tympanum) or eardrum.The human pinna is formed primarily of cartilage and is attached to the head by muscles and ligaments.igure 1 is a diagram of the human ear.

Hearing, structures and functions of the ear The pinna or ear shell is the shell-like part of the external ear, and it is made of cartilage and skin. The pinna directs sound waves from the outside into the external auditory canal (ear canal), which in turn channels sound waves to the tympanic membrane (known as the eardrum), causing it to vibrate.

Ulna Structure Edit. The ulna is broader close to the elbow, and narrows at it approaches the wrist. Close to the elbow, the ulna has a bony process, the olecranon process, a hook-like structure that fits into the olecranon fossa of the humerus.This prevents hyperextension and forms a hinge joint with the trochlea of the humerus.There is also a radial notch for the head of the radius, and the ulnar tuberosity to which muscles attach. Close to the wrist, the ulna has a styloid process.his prevents hyperextension and forms a hinge joint with the trochlea of the humerus.

Describe the structure and function of alimentary canal? The structure of the human alimentary canalThe alimentary canal is a long hollow tube which runs from the mouth to the anus .Together with several other organs, including the liver and the pancreas, it makes up the digestive system. The total length of the human alimentary canal is between 5 and 6 m, from anus to mouth.he serosa is a very thin layer, made up of connective tissue covered with a single layer of thin, smooth closely fitting cells. en833i2424lnnq. We can observe in detail each part of the human alimentary canal structure in this diagram.

Bicipital aponeurosis The bicipital aponeurosis (also known as lacertus fibrosus) is a broad aponeurosis of the biceps brachii which is located in the cubital fossa of the elbow and separates superficial from deep structures in much of the fossa. The bicipital aponeurosis originates from the distal insertion of the biceps brachii.While the tendon of the biceps inserts on the radial tuberosity, the aponeurosis reinforces the cubital fossa, and helps to protect the brachial artery and the median nerve running underneath.This protection is important during venipuncture (taking blood) from the median cubital vein.ome individuals (about 3% of the population) have a superficial ulnar artery that runs superficially to the bicipital aponeurosis instead of underneath it. These individuals are at risk for accidental injury to the ulnar artery during venipuncture.

tRNA Structure tRNA Function. The order of the nucleotides in messenger RNA determines which amino acids and in what order will incorporated into the protein product of the gene. The role of tRNA is to recognize a specific codon and to deliver the corresponding amino acid (the codon to anti-codon matching pattern).RNA Function.

Aponeurosis They have a shiny, whitish-silvery color, are histologically similar to tendons, and are very sparingly supplied with blood vessels and nerves. When dissected, aponeuroses are papery and peel off by sections.The primary regions with thick aponeurosis are in the ventral abdominal region, the dorsal lumbar region, the ventriculus in birds, and the palmar and plantar regions.Their primary function is to join muscles and the body parts the muscles act upon, whether it be bone or muscle.hey have a shiny, whitish-silvery color, are histologically similar to tendons, and are very sparingly supplied with blood vessels and nerves.

tRNA Structure A region within the 3D dimensional structure of the tRNA has a three-nucleotide sequence called the anticodon, which matches the genetic code of the mRNA codon. During the process of protein synthesis, mRNA anticodons bind to the codon of the mRNA and form temporary three base pairs structures.

Bacterial Structures and Their Functions Pili. The first external structure is the pilus (plural: pili). A pilus is a thin, rigid fiber made of protein that protrudes from the cell surface. The primary function of pili are to attach a bacterial cell to specific surfaces or to other cells.ne important note on fimbriae: there are some microbiologists that use the terms pili and fimbriae interchangeably. Both structures are similar and perform similar functions, blurring the distinction between the two.

Auricle Auricle. The auricle is also known as the pinna, and it is most commonly referred to as the ear. It is the most obviously visible part of the auditory system. An auricle consists of skin over contoured cartilage, and it is held in place by muscles and ligaments. Shape may differ by body type and person.he ear is the first part of the body to come in contact with auditory stimuli. Sound waves must pass over the auricle before entering the ear canal. Then, the waves pass through the tympanic membrane (eardrum) and into the middle ear.

- The basic function of the outer ear or pinna is to protect the eardrum (tympanic membrane). The outer ear also functions to collect sound waves to the eardrum through the ear canal. The second component of the external ear is the auditory ear canal or meatus.

tRNA Structure The primary tRNA function is  to deliver amino acids required for the process of protein synthesis. Transfer RNAs are carrying amino acids to the ribosome, where the actual protein synthesis takes place. The molecule is directed by the corresponding codon (a three-nucleotide sequence) in a messenger RNA (mRNA). This defines the role of the tRNA as a required component of protein translation.

Olecranon Structure [edit]. It is situated at the upper (proximal) end of the ulna, one of the two bones in the forearm. When the hand faces forward (supination) the olecranon faces towards the back (posteriorly). It is bent forward at the summit so as to present a prominent lip which is received into the olecranon fossa of the humerus in extension of the forearm. Its base is contracted where it joins the body and the narrowest part of the upper end of the ulna.
