Cerebrum = largest portion -left and right cerebral hemispheres divided by the longitudinal fissure -connected by t

Cerebrum. Cerebrum = largest portion -left and right cerebral hemispheres divided by the longitudinal fissure -connected by the corpus callosum -folded into ridges and grooves: grooves = sulci -sulci divide the cerebrum into lobes -ridges = gyri (gyrus).

Presentation Transcript


  1. Cerebrum • Cerebrum= largest portion • -left and right cerebralhemispheres divided by the longitudinal fissure • -connected by the corpus callosum • -folded into ridges and grooves: grooves = sulci • -sulci divide the cerebrum into lobes • -ridges = gyri(gyrus) • many gyri and sulci have specific names • e.g. Central sulcus • Frontal and parietal lobes

  2. Cerebrum • -cerebrum is comprised of white and • gray matter: • 1. white matter - neurons with • long, myelinated axons • -organized into tracts • -three categories of tracts • commisural – join areas between hemispheres • e.g. corpus callosum • b. association – joins areas within • a hemisphere • c. projection – joins cerebrum to brain stem

  3. Protection: CSF • brain contains fluid-filled chambers = Ventricles • Chambers in central passageway of the brain • 2 lateral ventricles, 1 third ventricle, 1 fourth ventricle • connects to the central canal which runs into the spinal canal • These chambers contain cerebrospinal fluid

  10. Right Atrium • Receives blood from 3 sources • superior vena cava, inferior vena cava and coronary sinus • Interatrial septum partitions the atria • Fossa ovalis is a remnant of the fetal foramen ovale • Tricuspid valve • Blood flows through into right ventricle • has three cusps composed of dense CT covered by endocardium Right atrium Interatrial septum Tricuspid AV valve

  37. pampiniform plexus Vas deferens testicular artery Epididymus Seminiferous Tubules Tunica Albuginea Tunica Vaginalis -testis: develop internally near the kidneys and descend through the inguinal canal during the latter half of the seventh month gestation -covered by several protection membranes 1. tunica vaginalis – serous membrane derived from the peritoneum, forms during the descent of the testes -injury to the testes can cause an accumulation of fluid within the membrane = hydrocele -allows for easier movement of the testes within the scrotum 2. tunica albuginea – internal to the TV -extends inward to divide the testes into lobules (200-300) -each lobule contains 1 to 3 coiled seminiferous tubules for sperm production
