The first is the femur in the upper leg, the tibia and fibula in the lower leg. the first is on the basis of their structure or on the basis of their function. The structural classification divides joints into 3 parts which are fibrous, cartilaginous, and synovial joints depending on the material composing the joint also the cavity's presence in the joint. synarthroses, amphiarthroses, and diarthroses are three categories of the functional classification. Sutures are fibrous joints that work on joining the bones of the skull together and it is can be found only in the skull.
Where is the primary somatosensory area located on the cerebral cortex? Name the primary action during REPOLARIZATION of an action potential. What structures make up the middle vascular layer of the eyeball? Give the names of the bones in the middle ear. The oval window is directly connected to which passageway (canal)?
| 1.1. Quadratus labii superior: Is a broad sheet, the origin of which extends from the side of the nose to the zygomatic bone. Its medial fibers form the angular head, which arises by a pointed extremity from the upper part of the frontal process of the maxilla and passing obliquely downward and lateralward divides into two slips. One of these is inserted into the greater alar cartilage and skin of the nose; the other is prolonged into the lateral part of the upper lip, blending with the infraorbital head and with the Orbicularis oris. The intermediate portion or infraorbital head arises from the lower margin of the orbit immediately above the infraorbital foramen, some of its fibers being attached to the maxilla, others to the zygomatic bone.
Supraglenoid tubercle- serves as the proximal attachment for the long head of the biceps 3. Infraglenoid tubercle- marks the proximal attachment for the long head of the triceps Distal Humerus 1. Trochlea- spool shaped structure located on the medial side of the distal humerus that articulates with the ulna to form the humeroulnar joint 2. Coronoid fossa- a small pit located just superior to the trochlea that accepts the coronoid process of the ulna when the elbow is fully flexed. 3.
There are generally three functions of the nervous system: sensory, integrative, and motor functions. Also there are diseases and disorders of the nervous system, some are life threaten and some aren’t. The Central Nervous System The central nervous system is made up of the brain and the spinal cord located in the dorsal body cavity. The brain is protected by the skull and is surrounded by the cranium. Meninges are connective tissue membranes that surrounds the CNS and along with it the cerebrospinal fluid.

Skeleton study- human A.) ------------------------------------------------- Frontal Aspect Frontal bone: The frontal bone is made of two portion squama frontalis and Pars Orbitalis Parietal bone: Parietal bones together form the sides and the roof of the human skull (4 angles/4 borders) Temporal bone: Temporal bones support the section of the face which is known as the temple. Sphenoid bone: Shape=butterfly, this bone is one of seven which combine to form the orbit Ethmoid bone: One of the bones which make up the orbit of the eye Lacrimal groove: Nasal bone: Two small size bones that form the bridge of the nose Perpendicular Plate of the Ethmoid: it forms part of the nasal septum Nasal concha bones: Shape = shell-shaped structure Vomer: Forms the inferior and posterior part of the nasal septum. Zygomatic arch: Cheek bone; formed by the zygomatic process of temporal bone and the temporal process of the zygomatic bone. Maxilla: The maxilla is two bones which are fused along the palatal fissure which forms the upper jaw Mandible: The Mandible is the bone which forms the lower jaw and holds the lower teeth in place Mental foramen: The Mental foramen is the name given to one of two holes which are located on the anterior surface of the mandible and allows the mental nerves and vessels passage.
PLEASE REVIEW THESE NORMAL CONCEPTS Chapter 42, Structure and Function of the Skeletal System 1. Cite the common components of cartilage and bone. Cartilage- avascular tissue that consists of cells called chondrocytes and extensive extracellular matrix. 95% of cartilage volume is extracellular matrix, which is the functional element of this tissue. A connective tissue sheath known as perichondrium overlies the fre surface of most cartilage.
List the general characteristics of vertebrates. The general characteristics of vertebrates are two unique features of vertebrates: a skull and a backbone. The skull forms a hard case for the brain. The backbone is composed of a series of skeletal segments called vertebrae (singular, vertebra), which enclose the nerve cord. 4.
