Table on Subarachnoid cisterns

Topics:

Cerebellomedullary cistern (magna)

Median pontine cistern

Interpeduncular cistern

Cistern of the great cerebral vein

Lateral pontine cistern or Pontocerebellar cistern

Ambiens cistern

Cistern of the lateral fossa

The walls of the cerebral ventricles

Written by a helpful professor to help in this difficult topic.

Excerpt:
"Choroid plexus locations: found in the roof of the 3rd and 4th ventricles and next to the central part and inferior horns of the lateral ventricles. (The choroid plexus is enlarged at the junction between inferior horn and central part; here it is called the choroid glomus). None is found in the anterior or posterior horns. The plexus in the lateral ventricle is the largest and most important and is continuous with that of the 3rd ventricle above the interventricular foramina. The lateral openings of the 4th ventricle (foramina of Luschka) also contain choroid plexus which protrude through them and secrete CSF into the subarachnoid space."

Histology hand-written notes for second-semester students

Here's a set of histology second semester exam notes not only becoming the first set of fully schematically illustrated histology second semester exam notes here at this medical school, but also the first set of histology second semester exam notes with complete organ descriptions preceeding the description of each separate histological preparation. 

Hand written notes developmental embryology

Although it's hand taken notes it's still extremely useful. Very illustrative drawings.

What's the Ductus Omphalo-entericus?

The ductus omphalo-entericus or allantois is a membrane that is present in the embryonic stage of mammals, reptiles and birds. The allantoic membrane is designed to help the fetus survive, removing waste from the animal. Both liquid waste and gases that the embryo have used are exchanged through this membrane. The allantois contains a network of blood vessels that the animal uses to remove waste products from the body.

Although many different animals have an allantoic membrane, they are not exactly the same. In birds and reptiles, the allantoic membrane not only removes waste from the embryo, but also helps to provide oxygen. Despite the appearance that the shell of an egg is solid, it can be permeated by oxygen. The allantois absorbs the oxygen that enters the egg and transmits it to the embryo.

Online Virtual Microscope

This is an amazing website created by the university of Iowa that let you zoom in and out, simulating a real microscope, from a wide selection of histological samples. Here we can find anything from Tongue-circumvallate papillae to adenocarcinomas! Link after the jump

Lower Limb Muscles: Origins, Insertions and Innervations. Summary of Joints.

Heres the summary of the lower limb muscles (origins, insertions and innervation) and joints (including pelvic girdle, knee and ankle joints)

Here's an excerpt:


"The Inguinal (Poupart) ligament: is formed by the inferior border of the aponeurosis of the
external abdominal oblique muscle. It extends from the Anterior Superior Iliac Spine to the
Pubic tubercle.
It has a medial point of attachment that spreads out as a broad surface known as Lacunar
ligament (Gimbernat ligament).
Laterally passing from this ligament along the Pectineal line of pubis is the strong fibrous
Pectineal ligament (Inguinal ligament of Coopers).
Between the inguinal ligament and the Iliopubic eminence is the Iliopectineal arch, that
separates the space between the inguinal ligament the anterior surface of hip bone into lateral
neuromuscular and medial vascular compartments."

Upper Limb Muscles: Origins, Insertions and Innervations. Summary of Joints.

Anatomy notes covering upper limb, with summary of origins, insertions and innervations of muscles. Also goes through joints (shoulder, glenohumeral joint, acromioclavicular joint, elbow joint and hand joints)


Here's an excerpt:

"The Superior Thoracic artery originates near the first rib and supplies the superior chest
muscles, the Thoraco-acromial originates as a trunk that pierces the costocoracoid
membrane with 4 branches: Clavicular, Acromial, Pectoral & Deltoid. The Lateral thoracic
artery runs on the lateral side of the chest on the Serratus anterior muscle with the Long
thoracic nerve. The Subscapular artery is the biggest branch and divides into 2 important
branches:
1. Circumflex scapular artery: which goes through the medial triangular space to the
dorsal scapular region around the lateral border of scapula to anastomose with the
Suprascapular artery (branch of the thyrocervical trunk of Subclavian artery) & the Dorsal
Scapular artery (branch of transverse cervical artery, found on the medial margin of
scapula) under the Infraspinatus muscle on the Infraspinatus fossa of the scapula.
Clinically, this is a very important anastomosis, in case of damage or obstruction of the
Axillary artery, the blood can still reach the upper limb via this anastomosis
2. Thoracodorsal artery: runs together with the Thoracodorsal nerve to supply the
Latissimus Dorsi muscle
The Anterior & Posterior Circumflex Humeral arteries anastomose also with each other
around the surgical neck of humerus. The posterior circumflex humeral artery goes behind the
neck of humerus via the Quadrangular Space together with the Axillary nerve & also
anastomosis inferiorly via the descending branch with the Profunda Brachii branch of the
brachial artery & superiorly with the Acromial artery via the ascending branch."
