Chapter 5 the skeletal system

It extends laterally and, on reaching the superolateral surface of the hemisphere, proceeds posteriorward between 1 the frontal and parietal lobes on its superior side and 2 the temporal lobe on the inferior side.

The diencephalon includes the 1 thalami with the medial and lateral geniculate bodies2 pineal body and habenulae, 3 hypothalamus, and 4 subthalamus. Laterally, it is limited by the bulging head of the caudate nucleus. The confluence was formerly called the torcular L.

Respiratory System

Amyotrophic Lateral Sclerosis ALS is a loss of motor neuron and this blocks the formation of neuromuscular junctions. The muscles aid in closing the oral cavity from the pharyngeal cavity and the oropharynx from the nasopharynx.

The terminal branches of the internal carotid artery are the anterior and middle cerebral arteries. At the starting position, the shoulders, the knees, and the balls of the feet should form a straight vertical line. Bone markings are important anatomical landmarks that reveal where muscles attach and where blood vessels and nerves pass.

Gouty arthritis, caused by the deposit of uric acid crystals in joints, typically affects a single joint. The department shall revoke a certificate of election to be exempt from coverage upon a determination by the department that the person does not meet the requirements for exemption or that the information contained in the notice of election to be exempt is invalid.

Many of the fibers to the pharynx and larynx are derived from nerve XI internal branch and travel by way of nerve X hence XI is "accessory" to the vagus.

Manner in which nervous, skeletal, and muscular systems interact to produce skilled movement using sensory information from internal and external environments. At least 60 days before the expiration date of a certificate of exemption, the department shall send notice of the expiration date to the certificateholder at the address on the certificate or to the e-mail address on file with the department.

The 14 facial bones are all paired maxillae, zygomatics, palatines, nasals, lacrimals, and inferior conchaeexcept for the vomer and mandible.

This region is concerned with autonomic and neuro-endocrinological functions. On the superolateral side, each posterior horn is bounded by a sheet of fibers the tapetum derived from the body and the splenium of the corpus callosum.

Lactic Acid[ edit ] Catabolized carbohydrates is known as glycolysis. To prevent this, tighten the abdominal muscles to tilt the pelvis and low back toward the ground. Hormonal activity control rests with hypothalamus and pituitary gland.

The anteroinferior extent of the floor of this ventricle is crossed by the optic chiasm. Hence the hemispheres lie above the orbitomeatal plane. Torque — Force that produces rotation.

The pattern of folding is variable, and it is necessary to remove the arachnoid to identify individual gyri and sulci.

With the exception of the palatoglossus, all the muscles of the tongue are supplied by the hypoglossal nerve. Arthrokinematics — Joint motion. In contrast, cardiac muscle which like skeletal muscle is also striated and smooth muscle both consist of single, discrete cellular units, each with its own nucleus.

The term hypothalamus is restricted functionally to the part of the brain comprising the floor and the inferolateral walls of the third ventricle.

It receives, directly or indirectly, a number of vessels from the interior of the cerebral hemispheres and also the basal veins. The autonomic nervious system supplies neural input to the involuntary systems of the body, like your heart. The anterior choroid artery passes backward along the optic tract and enters the choroid fissure.

The key drawing indicates related solid structures in parentheses. Concentric — Muscle is exerting force greater than resistive force, resulting in shortening of the muscle. The Lumbar Vertebrae Because vertebral segments increase in size and strength progressing caudally to sustain increasing weight load, the lumbar vertebra are relatively large (Fig.

).The centra are kidney shaped, larger in width than from front to back, and thicker anteriorly (except L2). CELLULAR ORGANIZATION OF SKELETAL MUSCLE FIBERS. Unlike most tissues, skeletal muscle does not consist of individual cells.

Rather it is formed from huge, multinucleate muscle fibers, which develop by fusion of many individual embryonic cells called fibers can grow by continued nuclear division within the fibers. Chapter 10 Anatomy of the Muscular System Figure Structure of a muscle organ.A, Note that the connective tissue coverings, the epimysium, perimysium, and endomysium, are continuous with each other and with the tendon.

Note also that muscle. Chapter The brain, cranial nerves and meninges Nervous system. The nervous system in general is described in chapter 3.

The divisions of the brain are summarized here in table This chapter is limited to a brief description of the gross structure of the brain, an account of the ventricles, and some general remarks on the cranial nerves, the meninges, and the blood supply. "Skeletal System" - Chapter 5: The Skeletal System Flash cards based off of the power point slides downloaded in the file "Skeletal System" as well as the notes written down for the class periods discussing the chapter.
